(Operator instructions)
I would now like to turn the call over to Ms. Jalene Hoover. Ms. Hoover, you may begin your conference.
Jalene Hoover - Director of IR & International Finance
Thank you, Shannon. Good morning, everyone. Thank you for taking the time to dial in. Tyson Tuttle, Chief Executive Officer, and John Hollister, Chief Financial Officer, are on today's call. We will discuss our financial performance and review our business activities for the second quarter. After our prepared comments, we will take questions. Our earnings press release and the accompanying financial tables are available on the investor relations section of our website at www.silabs.com. This call is also being webcast and a replay will be available for four weeks.
Our comments today will include forward-looking statements or projections that involve substantial risks and uncertainties. We base these forward looking statements on information available to us as of the date of this conference call, and that information will likely change over time. By discussing our current perception of our markets, the future performance of Silicon Labs and our products with you today, we are not undertaking an obligation to provide updates in the future. There are a variety of factors that we may not accurately predict or control that could have a material adverse effect on our business, operating results and financial conditions. We encourage you to review our SEC filings, which identify important factors that could cause actual results to differ materially from those contained in any forward looking statements.
In addition, it is not our intent that the non-GAAP financial measures discussed today replace the presentation of Silicon Labs GAAP financial results. We are providing this information to enable investors to perform more meaningful comparisons of operating results and more clearly highlight the results of core ongoing operations.
I would now like to turn the call over to Silicon Labs' Chief Financial Officer, John Hollister.
John Hollister - CFO
Thank you, Jalene. I am pleased to announce outstanding financial results for the second quarter. We achieved record revenue of $175 million, which exceeded the high end of our guidance range. As indicated on our April call, second-quarter revenue includes $5 million related to the sale of certain non-strategic patents. Excluding patent sale revenue, our total product revenue grew 5% sequentially to $170 million, also establishing a new record.
Non-GAAP earnings for the quarter finished at $0.75 per share above the high end of our guidance range.
Underlying our strong second-quarter revenue performance, IoT set a new record of $77 million, up 8% sequentially and 11% year on year. We saw particularly strong performance in mesh networking ICs and modules, Bluetooth Smart modules and 8-bit microcontrollers. IoT represented 45% of our Q2 product revenue.
Total Infrastructure revenue, including our timing and isolation products, was $36 million, or 21% of our second-quarter product revenue, up 13% sequentially and 18% year-on-year. Our timing products achieved record revenue in Q2 and will continue to benefit from a number of mega trends including the shift from enterprise to cloud computing in data centers and increasing bandwidth demand, which is driving 100-gig adoption in data center interconnect and metro area networks. Cisco is forecasting IP traffic to triple in the next five years.
Our isolation products delivered record revenue for the sixth consecutive quarter with growth significantly outpacing the market. We are taking share from our digital isolation competitors as well as incumbent optocoupler suppliers by offering higher performance, longer lifetimes and 10 times the reliability of optical based solutions. Our market opportunity is expanding as our isolators gain traction in a wide range of applications, including power supplies, electric and hybrid electric vehicles, solar inverters and motor controllers.
Broadcast finished the quarter better than expected at roughly flat performance to Q1 with record automotive revenue offsetting an expected decline in consumer. Total Broadcast revenue ended at $38 million, or 22% of second-quarter product revenue.
Access revenue declined as expected to $19 million, or 12% of Q2 product revenue.
We saw sequential growth in all geographies in the second quarter with particular strength in Europe. Looking at end markets, we saw the largest increase in Industrial, fueled by the ZigBee Smart metering ramp in Great Britain and increased sales of our isolation products. Revenue from Industrial end markets has grown nearly 20% year-on-year and we expect the momentum to continue. Strong performance in our Broadcast automotive products drove a sequential increase in Automotive end market revenue, and lower TV tuner sales drove a slight decline in revenue from Consumer end markets.
Worldwide distribution revenue increased over $10 million, or 10% sequentially, to approximately 69% of second-quarter product revenue. We are on track to expand our customer base by 20% this year, demonstrating the effectiveness of our broad-based approach to the market, including our Simplicity Studio development tools.
Non-GAAP gross margin in Q2 was above the high end of our target model range at 62.3%, which includes a 110 basis point benefit from the patent sale. Product gross margin finished strong primarily due to mix with growth in Infrastructure and Broadcast automotive products.
Non-GAAP operating expenses were in line with guidance at $73 million. Second-quarter R&D expenses increased slightly to $41 million with an expected increase in tape-out costs as we continue to expand our IoT portfolio. SG&A expenses declined marginally to $32 million with reductions in legal and payroll taxes offsetting increases in variable cost on higher profitability.
Non-GAAP operating income increased by more than $10 million in the second quarter to $36 million, or 20.5% of total revenue. We are pleased with the degree of operating leverage we were able to drive for the quarter. Due to strong revenue performance, superior gross margins and in-line OpEx, we achieved $0.75 per share non-GAAP EPS, exceeding the top end of our guidance range by $0.08. These results reflect an approximate $0.09 after-tax benefit from the patent sale, consistent with guidance.
Our non-GAAP effective tax rate was better than we expected at approximately 10.6% due to the geographical mix of income for the quarter.
On a GAAP basis, Q2 gross margin was 61.9%, R&D expenses were $52 million and SG&A expenses were $39 million. For the quarter, stock compensation expense was $11 million and amortization of acquired intangible assets was $7 million, both consistent with expectations. GAAP operating income for the quarter was $18 million, or 10.1% of total revenue. Second-quarter GAAP diluted earnings per share ended at $0.37, which was above our guidance range.
Turning now to the balance sheet, we ended the quarter with cash and investments of $251 million. Year-to-date cash flow from operations was healthy at $60 million and we continue to see only modest levels of CapEx required in the business at $6 million for the six month period.
Second-quarter year-to-date, we have completed over $38 million in share repurchases with an additional $62 million remaining authorized in the current program. The diluted share count for the quarter increased only slightly to 42.3 million shares, which is near a record low.
Accounts receivable declined to $72 million on day sales outstanding improvement to 37 days.
Net inventory grew to $56 million with turns declining to 4.7 times. This is in line with our internal target as we continue to position the Company for growth by maintaining adequate inventory levels.
I will now cover third-quarter guidance.
We expect third-quarter revenue to be in the range of $171 million to $176 million with growth in IoT, a seasonal peak in Broadcast, flat Infrastructure and a decline in Access.
We anticipate that Q3 gross margins will be approximately 59% due to strong performance from our Broadcast consumer and IoT wireless module products. Additionally, given expected continued growth in our IoT module revenue, we are lowering our gross margin target 100 basis points to a range of 58% to 60%. We are maintaining our non-GAAP operating income model of 20% to 25%. We have made progress this year toward achieving our target model and we anticipate this trend to continue with revenue growth into 2017.
We estimate Q3 non-GAAP OpEx to decline to $72 million with lower tape-out costs and continued judicious expense control.
We expect our Q3 non-GAAP effective tax rate to be approximately 11%. We anticipate that our non-GAAP EPS will be in the range of $0.61 to $0.67 and our GAAP EPS to be in the range of $0.27 to $0.33.
I will now turn the call over to Tyson.
Tyson Tuttle - CEO & President
Thanks, John. We are pleased to report exceptional second-quarter financial performance fueled by records in all of our strategic growth products including IoT, Infrastructure and Broadcast automotive, which now represents more than 70% of total product revenue.
IoT is approaching half of our total product revenue. A large and diverse market, the IoT presents a decades-long trend to connect everything in the world with end applications requiring wireless connectivity, integrated processing, ultra-low power and small footprints. The underlying challenge is how to best address this broad market efficiently and with a sustainable strategy.
Historically, we have offered highly differentiated components into larger systems with the goal of sustaining our market success with superior performance, coupled with barriers to integration and market diversity. The IoT represents a new paradigm for Silicon Labs where we can provide the complete system and control the integration path and add additional layers of differentiation in stacks, software, tools and simplicity.
We have created general-purpose, hardware and software platforms addressing the full range of applications that represent the IoT market. Our platforms include standards-based and proprietary wireless connectivity, highly integrated SoC devices and world-class software tools that make it easier for developers to add connectivity to their end products while optimizing for ultra-low power and long battery life.
During the quarter we expanded our Wireless Gecko SoC portfolio to include multi-band as well as multi-protocol capability, an industry first for the IoT. This flexible platform enables developers to work with one set of software tools while supporting proprietary stacks as well as standards-based protocols such as ZigBee, Thread and Bluetooth low energy. For example, connected device makers can now embed a combination of protocols such as Bluetooth to commission and configure devices with a smartphone and sub-GHz protocols to communicate over long range or legacy proprietary networks. Customers benefit from simplified designs, reduced cost and complexity and accelerated time-to-market.
We believe our Wireless Gecko SoC portfolio positions Silicon Labs as the leading provider of silicon, software and solutions for our target IoT markets. Our platform-based strategy allows us to quickly optimize for specific markets while serving a broad range of applications through simplicity and state-of-the-art software tools.
To meet the needs of a world that is increasingly software driven and to add value and differentiation to our products, we have directed the majority of our incremental R&D investments and M&A over the last five years towards the development of our software capabilities. Building on our software strength, we recently released our Connect wireless networking protocol, which enables developers to upgrade legacy proprietary systems with an easier to use, full featured protocol stack supporting sub-GHz and 2.4 GHz frequency bands. Connect runs on top of our Radio Abstraction Interface Layer, or RAIL software, which simplifies RF configuration and enables developers to easily migrate application codes to new ICs, essentially helping to future proof proprietary development.
Further leveraging our software expertise, we've launched a new development kit that helps IoT developers and makers race ahead in creating cloud connected "things" for the IoT. Our ThunderBoard React kit includes a demo board packed with temperature, humidity, optical and hall effect sensors, acceleration and Bluetooth low energy technology for connectivity. ThunderBoard React comes with a mini smart car that measures performance of the car, transmits data to the cloud through mobile devices and displays it in real-time for data analytics. The kit includes all mobile apps, firmware and open-source code for designers to start developing cloud connected applications right away.
Smart metering was one of the earliest areas of traction for our full portfolio of low power devices. These products incorporated our 8-bit MCU and 32-bit MCU in wireless devices, supporting both ZigBee and sub-GHz connectivity. Our momentum in the smart metering market continues as government agencies have mandated utility companies to offer advanced metering infrastructure systems as part of larger smart grid initiatives. For example, by the end of 2020, households and businesses across Great Britain will install around 53 million smart meters with approximately 30 million homes also requiring an in-home display and a communications hub for a total of 113 million units, and we expect to win most of that business.
ZigBee technology is ideal for smart metering. The protocol's simple, scalable, self-configuring and self-healing mesh networking capabilities offer utility and metering OEMs a mature, proven standard they can count on. It is also low-power, which helps -- allows metering products to last up to 15 years.
During the quarter, we also introduced a complete hardware and software reference design that reduces the cost and complexity of developing USB Type-C cables and adapters. The next leap forward in USB technology, USB Type-C supports higher data speeds, faster charging, greater flexibility and smaller form factors than previous USB connectors. For these reasons, USB Type-C is poised to become the connector standard of choice for mobile devices, PCs, docking stations, monitors and other consumer electronics products with an estimated 2 billion USB C enabled devices employed by 2019, according to IHS.
In August will celebrate our 20th anniversary. We have a long history of leveraging our mixed-signal and RF design expertise to deliver highly integrated solutions. From our groundbreaking DAA to the world's first CMOS RF synthesizer, advanced timing solutions, radio and TV tuners, digital isolators, microcontrollers and wireless SoCs for the IoT, we have consistently demonstrated our ability to pioneer innovation and achieve market leadership.
Our vision is to connect people, devices and data across multiple markets and applications. We are beginning a new chapter in the creation of a more connected world where the intersection of cloud computing and the proliferation of connected devices will transform our lives and economy in dramatic ways, and Silicon Labs is at the heart of it.
We are executing on an aggressive roadmap to leverage the potential of these trends. Our strong second-quarter results and third-quarter guide are evidence of our progress and position us well for growth.
Thank you for your time and attention. Before we take your questions, I would like to turn the call back to Jalene. Jalene?
Jalene Hoover - Director of IR & International Finance
Thank you, Tyson. Before we open the call for the question-and-answer session, I would like to announce several conferences that we will participate in during the third quarter, including Pacific Crest's 18th Annual Global Technology Leadership Forum in Vail on August 8, Citi's Global Technology Conference in New York on September 7 and Drexel Hamilton's Telecom, Media and Technology Conference, also in New York, on September 8.
We would now like to open the call up to your questions. To accommodate as many people as possible before the market opens, we ask that you please limit your questions to one with one follow-up. Shannon?

Craig Ellis, B. Riley.
Craig Ellis - Analyst
Thanks for taking the question and congratulation on the operating margin performance in the quarter. I just wanted to follow up on the comments about isolation share gain from both digital and optocoupler competitors. Can you go into more detail there and provide us with some more color on how you see isolation playing out as we look -- go over the intermediate term, say, through the 2017 time period?
Tyson Tuttle - CEO & President
Craig, this is Tyson. Our isolation products are the evolution of a technology that we've been developing for 20 years. It started with our DAA technology where it was proven out with all sorts of lightning and real-world application examples. And so we've developed a very robust isolation technology that for the last decade we have been applying towards the replacement of opto couplers in the systems that require higher levels of performance, higher levels of isolation voltage, higher levels of reliability and faster speed. So it offers a wide range of advantages over traditional technology, and we have had superior specs and parameters than the competing solutions from TI and ADI in particular.
We also -- it's a silicon-based solution, and we are able to integrate additional circuitry around the isolation barrier to solve specific problems around motor controls, power supplies, inverters, and so that has given us a really strong position in the market, and so we've won a lot of business in data centers and hybrid-electric vehicles and solar energy and a lot of different other applications. It's a broad -- it's actually one of our broadest businesses. We have a large number of customers there, we have a very rich penetration into the distribution channel and very good traction in the market. We've been growing that business -- it's actually one of our faster growing businesses. It is a sub-category of Infrastructure, but in the 30%-plus range of over multiple years we've done six consecutive record quarters now, and we expect that type of momentum in isolation to continue to play out as we go into 2017.
Craig Ellis - Analyst
That's very helpful color. I appreciate it, Tyson. The follow-up is tying together some comments around the IoT segment and then John's comments on the gross margin range. So within IoT we have modules, which are growing but I believe a lower margin business. We've got the launch of the SoC's, which is a very unique capability and with small revenues now but likely growing and then there are more discrete solutions. What I'm hoping you do is provide some color around how you see those different types of businesses evolving over time and what the gives and takes are relative to gross margins and the gross margin range that John talked about.
John Hollister - CFO
Sure, Craig. This is John. We've seen strong performance in our module product lines this year and see that trend continuing, which is really the primary impetus to the adjustment on the gross margin target model that we provided this morning. Over time, we are very well positioned to continue to cost down and remain very competitive in the market, and we think with the advent of the SoC strategy, we're very well positioned competitively from that perspective. So the module content is really the primary driver on the module margin adjustment.
Tyson Tuttle - CEO & President
Yes. This is Tyson. Just to remind you, the module business came from our two acquisitions last year of Bluegiga, which brought in Bluetooth smart technology, and then also Telegesis, which had a number of ZigBee modules into the market. And we were -- had made the decision to bring that in through M&A. They had leading positions in the market and we've seen very good traction with that. The rationale for that move was that the modules are actually very appropriate for selling into the channel. It makes the RF performance guaranteed. The antenna is integrated. You have pre-certification. So it makes it easy to support and gain scale and leverage across the broad market. In addition, with the -- now our SoC's are inside the majority of the modules and that shares is increasing as we go forward, and it allows us to put the -- for high-volume accounts to put the SoC's directly on the board and make a soft scalable from both the module into the -- into an onboard design, and so that lets us optimize both the support side as well as the margins going forward.
So we thought it was very important to get into the module business. We did know that there was additional content in the modules, so it's not -- it's less silicon content so the margins are a little lower, but overall, we think it is a constructive and healthy piece of our business and we are seeing good success in the market as evidence of that.
Craig Ellis - Analyst
Thanks, guys.
Operator
Tore Svanberg, Stifel.
Tore Svanberg - Analyst
Yes, thank you. Nice quarter. I guess a follow-up to that last question on the SoC in the gross margin. So is it my understanding that as SoC's become a higher percentage of the revenue, that there could be some potential upside to gross margin? Or, is this sort of the new norm going forward?
John Hollister - CFO
Yes, Tore, this is John. New norm is a healthy way to view this. The SoC's would be higher margin than the module content. Over time we will see how the IoT margins play out, but, bear in mind, also we have Infrastructure projects operating at above our corporate average margin and we do expect that to continue to grow as well. So, there's puts and takes even within IoT across the various product lines. We thought it judicious to go ahead and update the model, given the trends that we are seeing. And our goal is to drive revenue growth and generate higher operating leverage with judicious expense control as we move through the course of 2017.
Tore Svanberg - Analyst
Understood. Thank you. And as my follow up, could you elaborate a little bit on your comments about Q3 Broadcast? I think you said that a peaking of Broadcast. And maybe you could also elaborate a little bit on the TV turner business, sort of what those dynamics are now, especially as it relates to pricing, and as this business now becomes small enough where it is becoming less and less of a headwind for the Broadcast business. Thank you.
John Hollister - CFO
Sure, Tore. This is John again. So as we had indicated earlier this year, we had some tough year-on-year comparisons in the first half of 2016, given the particularly strong performance in Broadcast, particularly in the video business in the first half of 2015. We are seeing our way through that phenomenon now and actually seeing some upside in third quarter in the video business. That's the result of a couple of factors -- one being regain of share, some of which was impacted by the Cresta lawsuit issue and just overall better penetration of the China market and as well as the Olympics in Rio this year are driving some degree of additional demand. We do see that as a seasonal peak in third quarter and would expect that to tail off some in the fourth quarter, just due to seasonality. So overall, once we're past the first half comparisons, we are seeing a reasonably healthy video market here now more stable.
Tore Svanberg - Analyst
Great, thank you.
Operator
Blayne Curtis, Barclays.
Blayne Curtis - Analyst
Thanks for taking my question and nice job on the quarter. I just wanted to follow back on the gross margin. So you're guiding to the midpoint of that range. I would assume that IoT is going to continue to be -- outgrow your overall business. So just curious when you say that the ongoing range here, what are the other offset? Are you able to improve the margins on the modules side or is it really Infrastructure that helps in the mix? What are the moving pieces that keep you in the midpoint of that range?
John Hollister - CFO
Yes, it is both of those, Blayne. This is John again. IoT now is a bit below the corporate average with the higher module content. So -- and clearly we have ongoing cost improvements around the modules themselves. We have ongoing cost improvements along the underlying chips and strength in Infrastructure as some of the major factors affecting that landscape.
Blayne Curtis - Analyst
Okay, and then just another clarity on the last question -- so you are saying Broadcast is up in Q3 but that's a peak and then should decline in Q4? I just want to understand what peaking meant because I originally thought it was down, and as you look to December, just any color on just overall seasonality would be helpful.
John Hollister - CFO
Sure. So when we say peak, we mean sequentially for the year -- for this calendar year, and it's really just driven by seasonal demand on the consumer market. That's really the primary factor from annual seasonality, and we will be able to give some additional color, of course, on the next call as how things shake out for the fourth quarter.
Blayne Curtis - Analyst
Thanks.
Operator
Matt Ramsay, Canaccord Genuity.
Matt Ramsay - Analyst
Yes, thank you very much for taking my questions. Good morning. I guess going back to the IoT business and an earlier question that did a good job of talking about the different drivers going forward, Maybe, Tyson, you could give us a little bit of an update with the ramping modules business of what we should think about as a target growth rate for revenue in the IoT business going forward. I mean, it's always hard to guide that stuff too far, but if the margins are a hair lower, it would seems like the addition of the module business could drive some of the elastic demand in the channel. So just trying to get an update on the top line. Thanks.
Tyson Tuttle - CEO & President
So in terms of the drivers for IoT, we've got a broad range of applications. We've got a number of high-volume applications as well as success in the channel with the modules being very appropriate for the channel. If you look at the module margins and the quantity of revenue that's coming from that and the fact that we have moved our gross margin target model down. It was 60 to 62 and now it's 58 to 60. That 2 point drop is entirely attributable to the lower gross margin out of the module business. So the change in model does reflect the additional module content. We do have cost reductions in place to continue to make those products more competitive in the market and to continue to drive success with those. The modules are especially important in the channel, it makes the products more attractive to sell, very easy to sell. There is no RF support for antennas and compliance required with the modules.
So it's a very popular product -- set of products and it's an important part of our strategy going forward. So while it does come at a lower gross margin percent -- actually when you sell a module the gross margin dollars are higher. So as we have more growth in the modules, it will provide a little bit of a lower overall gross margin, but the gross margin dollars are as an accretive number there, and we believe it will drive significant success, both in the channel with the broad customers, but also as those customers move into high-volume, our ability to move those onto SoC-type designs.
Matt Ramsay - Analyst
Got it, got it. I think that last point about gross margin dollars was what I was really trying to get out. And then as a follow-up, I thought it interesting your quite bullish commentary in your prepared remarks about the UK rollout of the smart meter platform. How are you thinking about that in the context of the Brexit decision? Is it impacted one way or another? Just kind of unclear about what that impact might be for domestic investment in the UK. Thanks
Tyson Tuttle - CEO & President
The UK smart metering rollout is something that we've been working on for three to four years. This has been the program with the UK government and the utilities, and actually, as a result of Brexit, if you believe that there would be some additional stimulus into the economy, it might be something that they accelerate, but I certainly do not see any reduction in ordering patterns or any hesitation to continue with that rollout. It's something that's driven by the government and by mandates and we believe that it has got a lot of momentum in place. That rollout will happen over the course of four or five years as it deploys across the UK.
So it is an exciting opportunity. I think if you just look overall at the impact of the Brexit and the stronger dollar, it does also drive a bit of favorability on -- with foreign exchange in terms of our operating expenses. But overall, we think that the impact is minimal, if not somewhat positive.
Matt Ramsay - Analyst
Great, thanks. Good to see the nice results.
Operator
Anil Doradla, William Blair.
Anil Doradla - Analyst
Congrats from my side, too. So a couple questions now on the $5 million patent sale. Obviously you talked about it a little bit last quarter. Tyson, and you give us a little bit color, and going forward, is there like a kind of a patent strategy in terms of maybe divesting some of your patents, given the amount of IP you guys have developed over the years?
Tyson Tuttle - CEO & President
So the $5 million patent sale came -- it was in our Infrastructure product area. We haven't had to talk to specifically about what patents, but these were some patents that were nonstrategic in a product area that we have deemphasized. They were valuable patents and were able to sell those at a favorable price. We continue to view IP sales as opportunistic. It is part of a strategy that, if it make sense, we will do it, but it's not something that we plan on an ongoing basis. I would add that we have a very strong IP position. We have over 1,500 patents pending in issued and continue to file new IP at a fairly rapid clip as we develop new products and technologies over time. So it is an important component in the value of the Company and in terms of the competitive positioning of the Company,but in terms of monetization, it is something that we treat opportunistically.
Anil Doradla - Analyst
And on the timing front, clearly things are improving there. Can you share some insights on what's going on perhaps on the wireless side, on the wireline side, any kind of incremental color in terms of the demand environment, especially from Asia and China versus North America?
Tyson Tuttle - CEO & President
So we did hit a record quarter in timing -- passed a very nice milestone there, and saw good strength in our core data communication customers -- So, this is wireline, optical networking, high-performance where our traditional business has been. We are seeing some uptake in data center and in wireless, but that is still a smaller portion of revenue and actually represents a good growth opportunity for us for that set of products, and we are optimizing our portfolio somewhat for those specific market segments.
So we see the growth in that business continuing to layer on. We believe that 2017 should be a good year for timing as well, but I think that as we are coming into the second half, we're seeing maybe more kind of nominal demand out of the timing customers, and so we think that in terms of timing the -- in Q3 it will be a smaller portion of the product revenue mix. And so that does provide a bit of a headwind on the overall corporate gross margin, but in terms of the competitive positioning and the strength of the end market and our product developments, we think that that is solid and actually increasing as we go forward into next year.
Anil Doradla - Analyst
And, Tyson, one final one. I remember like 2, 2.5 years ago you guys introduced kind of a high-volume, more consumer-oriented using some MEMS technology and all that stuff. Can you share some -- how that is playing out and how much did that contribute in your results?
Tyson Tuttle - CEO & President
The consumer portion of the timing business has been deemphasize, and in particularly, the CMEMS products we believe are -- that that was not coming in as an attractive business for us. We have emphasized the high-end, higher performance aspects of our timing products were we believe we can drive profitable growth and have a significant competitive differentiation and advantage
Anil Doradla - Analyst
Fantastic. Thank you.
Operator
Cody Acree, Drexel Hamilton.
Cody Acree - Analyst
Thanks, guys, for taking my questions and congratulations on the progress. Tyson, on the module strategy in IoT and the change in the gross margin targets, is there a way to quantify the trade-off that you think you are getting in growth rate for taking a lower gross margin, and then, as you look at the operating margin of the business, I would think that you're able to maybe get better leverage for your R&D across multiple players? So while you're lowering margins, are you able to actually either improve or keep stable operating margins on those same products?
John Hollister - CFO
Hi, Cody. This is John. I will start out here. We don't have specific numbers to quantify the trade-off precisely in that way, but I would just start by pointing out that we believe market itself will be addressed with a high percentage of module content. We've seen industry estimates that up to 50% of the Bluetooth market would be addressed in the form of modules and roughly 20% of the mesh networking market would be addressed in modules. So this really is important incremental business and it's important for our customers to get an effective on-ramp to the IoT, and, yes, we agree with the thesis of what you're saying. We should generate more operating leverage with those modules sales.
Tyson Tuttle - CEO & President
I think are you also have to look at how to leverage the silicon and software developments across the overall market. If by having a module offerings we are able to make the customer experience, we are able to maintain the connection with the smaller customers, they are developing with our tools and those same tools, the same software, the same SoCs are then usable on board. So we do get significant leverage of our investment in R&D across the module in the silicon content, and I think we also get additional leverage out of the channel in terms of better support. It's easier to support those products, and so it takes less effort to sell them, less effort to -- in terms of field application engineering.
And so those are really the challenges of adjusting a broad market and addressing IoT. I talked about that in the script a little bit -- about how do you make money and how do you drive good profitability out of a broad market, and it requires leverage across multiple applications. Our SoC platforms need to be general-purpose enough to be used in a lot of general applications, but also competitive in terms of cost and highly differentiated in a lot of the vertical applications, and the modules are an important piece of that general-purpose strategy. And you also need to get leverage out at the channel and out of customer support. We are growing our customer count by 20% per year, and we're certainly not adding 20% of our sales force and our applications engineering or R&D per year.
And so getting that leverage and having this whole mindset of simplicity, of making these products easy to use, out-of-the-box so that customers can just pick them up and run with them, I think provides a significant advantage for us into the market, and it's something that we've been focused on for quite some time, and I think we're getting better and better at it as time goes on.
Cody Acree - Analyst
And, Tyson, you mentioned that increase in customers. I guess if you are not able to maybe quantify an increase in maybe IoT growth rate, are you at least seeing a tangible enough increase in design win activity, that is obviously causing you to make structural changes in your gross margin expectations? So that whether it is ready to translate to revenue, there is already some tangible numeric increase in your design traction that's causing this change.
Tyson Tuttle - CEO & President
Well we have now significant portion of our wireless business going through modules, and that's responsible for the lower overall gross margin because we're carrying additional components within the modules that we don't markup as much as we would markup the SoC. The gross margin dollars are higher. Last year we grew our IoT business by 26%. In the first half of this year it was a little bit less than that, but we should notch in close to 20% for the year, and it's continuing to see strong design win traction around a lot of the vertical applications within IoT such as smart home, security. You've got wearables. You've got lighting.
There's a lot of industrial applications around metering. Certainly we talked about the UK smart energy ramp, but there's a broad set of applications, but the design win traction that we're seeing continues to support these strong double-digit growth rates in the business and I think also validates our investment strategy around modules, around incremental R&D investments, around IoT and having moved out of the more areas such as Broadcast and Access and now having 70% of our revenue coming out of these growth products positions us well going forward. I think that we have gone through this transition from a component-based Company to more of a system Company, driving close to 50% of our revenue now out of IoT, and the market traction we're seeing, we're quite pleased with where we are positioned strategically.

Thanks for taking my question. The first one's for John. For Q3 I've got OpEx down slightly to get to the EPS range, and then as you look at December, do you think you have the potential to go belong the 5% OpEx growth target you've laid out for the full-year, and could you talk more about the cost reduction opportunities available? Thanks.
John Hollister - CFO
Yes, Ian. That's right. We guided Q3 at $72 million, which would be $1 million below where we landed Q3. The guide on the total year from the beginning of the year was around 5%. I would hold that. It could come in slightly favorable to that. But it is roughly at the 5% level, perhaps slightly below.
Ian Ing - Analyst
Perhaps, slightly below. Okay, great. And then could you talk about perhaps the waiting of IoT versus Broadcast in terms of driving the revised gross margin range? It sounds like Broadcast peaking right now -- perhaps more of a contributor that could fall over time. IoT, the channel business, that sounds like it has a lot of runway -- perhaps the current waiting and how that waiting plays out over time.
John Hollister - CFO
Yes, so the general trend would be Broadcast consumer would be declining over time with growth in Broadcast automotive. So there's a bit of a change underway within the Broadcast portfolio itself, but overall, the IoT, in terms of dollar growth in particular, is where we see the highest contribution to our overall dollar growth in the future.
Ian Ing - Analyst
Okay. Thank you very much.

Thanks for letting me ask a question. Really quickly, Tyson, what exactly are you guys selling in this smart metering product at UK? Is it just ZigBee and the module solution, or are there other things that you contact on such as microcontroller and other stuff?
Tyson Tuttle - CEO & President
The primary product that we are selling into the UK smart energy market is the ZigBee SoC. It does include the microcontroller functionality, but it is the ZigBee SoC and, in most of the cases, it is a module.
Harsh Kumar - Analyst
I got you, and a lot of questions on your gross margin going forward. I'm curious if there are things that you can do, if there are aspects of cost that you can cut out or perhaps even scale? I know modules get a lot lower gross margin, but you are -- you do have significant software capability that you're perhaps able to layer on? Are there aspects such as scales or software tack-ins that could offset in the future? Perhaps this shift towards module and the gross margin there and that's happening to you -- your business.
Tyson Tuttle - CEO & President
So, there are significant cost improvements that we can drive into the module market. Actually there's significant differentiation that we can drive into the module market because we have control of the silicon, and in designing the silicon, we can keep the module and the cost of the module in mind. In my view the package -- or the module just looks like another package for the part, although it does greatly simplify the RF design and support requirements. So we can drive size improvements. We can drive cost improvements with the modules because we also control the silicon, and the software -- if you're looking at in terms of monetization in software, that's something that has been traditionally difficult for silicon companies to achieve is to be able to charge for software. Although you can think of the software and the differentiation in the software further differentiating the product.
But we are trying to understand how to value and how to potentially charge for software over time. I think that that's a significant opportunity as you integrate security into the devices, as you can individually address them, as those devices get connected, as the devises have general functionality that can be enabled in the field. There are ways to continue to differentiate and potentially monetize software. Today that's a small part of our business, but it's something that I think is a significant opportunity, in particular in the IoT area as you've got those different functionalities and demands from the customers. I would also think that just on the margins you've got -- there's a mix both within IoT and the different applications, different flavors of wireless between 8-bit, 32-bit. So the mix does drive a little bit of the gross margin within IoT.
And then you have got the mix at the corporate level. You've got Broadcast consumer at a somewhat lower margin than the corporate average that is declining. You've got Broadcast automotive above the corporate average that is growing. Timing and isolation both above the corporate average, those are growing very nicely. So you've got, again, mix that as quarters come and go, we will have a little bit of variation, but there is no denying the fact that A, the module is a larger fraction of our content and that has essentially provided a drag of about 200 basis points on the overall gross margin. It is also, I think, giving us a lot of leverage in terms of the growth.
And I'd also say that we have leading portfolio of products. They are market-leading in terms of competitiveness, and we have taken no prisoners in terms of gaining market share in the strategic markets, and that volume will drive growth; it will drive further cost improvements with volume and we see that playing out over time, but it is our goal to be leaders in the segments in which we're competing, in particular around IoT and Infrastructure.

Rajvindra Gill - Analyst
Yes, thank you for taking my questions. I appreciate it. Just kind of a big picture question on the competitive landscape -- specifically in IoT. I wanted to get your thoughts on that. Clearly there's been consolidation that's been going on in IoT, both larger companies acquiring others as well as some companies buying carve-outs of larger entities. So I wanted to see what's your thought process on the competitive landscape in IoT and what you think are going to be the kind of key differentiators to win in this market.
Tyson Tuttle - CEO & President
I believe our competitive positioning has never been better, both because of our progress and our internal developments and getting out our SoC platforms and building out our SoC platforms and building portfolio of products and software, but also as a result of the consolidation. We've seen Atmel being acquired by Microchip. We saw the merger of NXP and Freescale. We saw the sale of the Broadcom IoT assets to Cypress, and I think that each one of these provides an opportunity for us to gain share as those companies integrate. I think that it's one thing to say that you're putting two things together, it's another -- there's a lot of devil in the details of how that comes together in terms of culture, in terms of roadmap, in terms of which process technology things are on, and I think that that provides a lot of distraction for the competition and provides an opportunity for us to gain share.
I think that the vertically oriented companies just compared to a year ago -- I think that certainly we've seen Broadcom exit in sale of that set of assets to Cypress. I think that certainly makes that less of a competitive threat to us over time. I think that in the case of Qualcomm and their focus on cellular, and I think less emphasis on the markets that we are going after, takes them out of -- they are not really on the radar as much. And I think the overall reduction in the number of competitors in the broad market -- the micro controller companies is also an advantage and coupled with the distraction that those companies are seeing as they are integrating together. So I believe that, overall, our competitive position, we remain very focused and focused in the market and focused with customers and see this as a position of strength for us.
Rajvindra Gill - Analyst
On the IoT, in terms of the different connectivity standards, their multiple standards, I wanted to get a sense from your if you could maybe talk about what applications are going to require which standards and how you're positioned in each of those applications from a connectivity portfolio perspective.
Tyson Tuttle - CEO & President
So our traditional strength has been in both sub-GHz connectivity, which is mainly used in a lot of industrial markets and we have continued to strengthen our position there with -- we talked about our Radio Abstraction Interface Layer that we introduced to help customer port their stacks onto our new SoC platforms and to make that easy, and that's really the result of a decade of work on understanding the requirements in developing chips, and that functionality is now integrated into our SoCs. We also have had a long history in mesh networking ICs, so this is ZigBee and Thread. The UK smart meter rollout, for instance, is on ZigBee. That set of standards is good for robustness, for low energy, for command-and-control type networks. You've got home automation, security, metering, lighting being very significant markets for the mesh networking technology where a lot of the devices are either battery-operated or need to have a robustness and a scalability and a range that is uniquely addressed by the mesh networking technology, and we're seeing significant growth and adoption of those in devices as well as within gateways in the operators and in commercial. Gateway is integrating IoT functionality as part of the internet access that goes into the home and into businesses.
So that's a very positive trend, and I think that the need for that low powered mesh networking is unique and is not served by the other ones, which are -- you've got Bluetooth, which is primarily used today for connection between an end device and a smartphone. So it's not really a networking technology, it's trying to move towards being a networking technology, but it has traditionally been used for audio, and with the advent of Bluetooth low energy -- which is where we have focused our efforts into a wide variety of connected device applications outside of audio with wearables, for instance, being a particular use case for Bluetooth.
So that's an important part of the portfolio. Again, our multi-protocol SoC can speak proprietary sub-GHz, it can speak mesh networking and it can speak the Bluetooth low energy source. So our silicon platform and the software can support multiple protocols in the same device, and that makes it very scalable across -- sufficient from our R&D perspective, but it's also scalable across a lot of applications, and combining them in a lot of applications is a key piece of differentiation for us.
So those are the primary focus for us have been on the low power type of standards. You've also got Wi-Fi technology where we have some modules and have some experience. Those are typically in higher data rate applications. And then you've got some of the wide area networking technologies like LTE, you've got SIGFOX, you've got LoRa, and those are used to talk directly to wide area networks, and we have not traditionally played in those areas. So we've focus on the low power, lower data rate applications, which are really the sweet spot for a lot of these IoT applications

Hi, Tyson. Hi, John. You talked about the modules being -- the smart meter business being modules. I'm wondering which end-markets tend to be more module centric versus chip centric and what percent of IoT do you think will be modules two or three years out?
Tyson Tuttle - CEO & President
Could you repeat your -- the last part of your question. It was mumbled.
Suji De Silva - Analyst
Sure. What percent of the IoT business will be more modules in two or three years?
Tyson Tuttle - CEO & President
Okay. So if you look at the modules are going after a lot of broad applications. So metering for instance is -- they have integrated modules. You've got a lot of the Bluetooth applications outside of the space constrained ones. So anything that's lower volume, like say 100,000 units and below is going to tend to go towards modules, and it's not specific to a market, it's really in terms of the size and sophistication of a customer and how much R&D capability they have versus that -- spending a little bit more on a module and being able to avoid that R&D expense. So it's -- for the highest volume applications like lighting, you could see that going down in the board. For a very space constraint wearable, high volume applications, you could see that going down on the board.
But I believe that modules are going to continue to be an important fraction of the IoT wireless business. We don't break that out separately in terms of mix, but I believe that the fraction of our IoT business going through modules is going to continue to increase over time, although I never see it becoming a majority of the wireless piece of the IoT business. So we have got a mix of microcontrollers and wireless, and then you also have modules as an important component there, but you're going to continue to see significant growth on modules as well as those other areas within IoT.
Suji De Silva - Analyst
Okay. And then on the multi-protocol wireless products. What combination of wireless protocols are you seeing near term traction for most?
Tyson Tuttle - CEO & President
A lot of the ZigBee applications with -- like in terms of provisioning, in terms of getting that device on to the network, it makes it easier to have Bluetooth capability integrated into the same device. So when you first pair the device with the network, it goes into Bluetooth mode, talks to a smart phone, you get it that up and then it switches over to ZigBee. You can also see those applications being used for things like beacons or continuing to talk to a smartphone directly as well as the network, so that combo is quite popular.
We also see a lot of customers in the industrial space wanting to do the same thing. So a lot of the proprietary sub-GHz customers being able to speak Bluetooth as well as proprietary -- that is attractive. We have a number of customers wanting to talk to both a ZigBee and Thread network. Or even you can do ZigBee and a sub-GHz network of some customers there. So it really just provides the nice Swiss Army knife for the customers to mix and match the protocols for the use cases and to add additional functionality to the devices to make them easier to use and more differentiated out into the market, and I think that that set of capabilities is an important part of our connectivity strategy going forward. It's very attractive to the customers.
