Thank you, Kishore. I will first review our results and then briefly discuss our outlook.
In summary, Q2 revenue was a record $24.4 million, as Kishore mentioned, above the high end of our guidance of $24 million. This represents sequential growth of 18% and 35% year-on-year. As Kishore noted, net revenue for the second quarter was driven by very strong sequential performance in cable, stabilizing revenues for terrestrial applications and strong design win momentum across a wide range of product areas.
Now moving to the rest of the income statement. GAAP and non-GAAP gross profit for the second quarter were both approximately 62% of revenue, at the high-end of our prior guidance of 60%, plus or minus 2 percentage points versus 60% in the first quarter of 2011 and 63% in the year-ago quarter. The increased sequential gross margin is due not only to favorable mix changes, but also the great work by our supply chain and engineering teams to achieve meaningful cost reductions.
Our Q2 GAAP operating expenses were $17.6 million, which includes $2.3 million of stock-based compensation, $1.5 million for an accrual related to our performance-based bonus plan for 2012, which if achieved, will be settled in stock and 2013, and $0.5 million of professional fees and potential penalties attributable to our ongoing export compliance matter and the patent litigation matter with Silicon Laboratories that was initiated in the quarter.
Net of these items, OpEx was $13.3 million which is $1 million lower than the prior quarter and lower than our prior guidance of $14 million. Q2 GAAP OpEx included $11 million of R&D expenses which includes a stock-based compensation of $1.5 million and $1 million related to the accrual mentioned earlier, related to our performance-based equity bonus plan for the -- for 2012.
The decline in R&D expenses quarter-over-quarter was due to certain engineering expenses pushing into the third quarter. The second quarter GAAP OpEx included $6.6 million of SG&A, which includes $0.8 million in stock-based compensation and the $0.5 million for professional fees and potential penalties attributable to our ongoing export compliance matter and patent litigation with Silicon Laboratories.
At the end of the first quarter 2012, our headcount remained essentially flat versus the first quarter at 250. GAAP loss from operations was $2.5 million in Q2 compared to $6.5 million in the prior quarter, and GAAP loss from operations of $5.7 million in Q2 of last year. GAAP loss per share in the second quarter was $0.08 on a fully diluted shares outstanding of $34.5 million. GAAP loss per share includes $2.3 million in stock-based compensation expense, $1.5 million for an accrual related to our performance-based bonus plan for 2012, which, if achieved, will be settled in stock in 2013, and $0.5 million in professional fees and potential penalties attributable to our ongoing export compliance matter and the patent litigation with Silicon Laboratories. Net of these items, our non-GAAP earnings per share was $0.05.
Moving to the balance sheet and cash flow statement, our cash, cash equivalents and investment balance was approximately $84.3 million at the end of the second quarter 2012 compared to $83.4 million in the prior quarter and $85.7 million at the end of 2011. Our cash generated in operations in the second quarter of 2012 was $1 million, approximately $2 million better than in the first quarter of 2012, and approximately $1.3 million better than the year-ago quarter.
Accounts receivable totaled $15 million at the end of the second quarter compared to $11.1 million in the prior quarter. The day sales outstanding for the first quarter were approximately 56 days or 7 days higher than the previous quarter, and 42 days at the end of the year-ago quarter. The increase in DSOs was a function of customer mix as we move to more direct sales for cable customers, resulting in less favorable payment terms, as well as experiencing some slow paying by our customers in Asia.
As a reminder, we only recognize revenue on a sell-through basis, so we are not subject to revenue fluctuations caused by changes in inventory distributor -- sorry, distributor inventory levels. Our in-house inventory at the end of the quarter was $8.5 million, up approximately $1.7 million compared to the $6.8 million in the previous quarter, and up approximately $0.5 million versus the $8.1 million at the end of 2011.
Our inventory turns improved to 4.9 in the second quarter compared to 4.5 turns in the first quarter. Our increasing inventory levels, a result of electing to build inventory of new products ramping to support upside opportunities, primarily in cable and hybrid TV.
That leads me to our guidance. We expect revenue in the third quarter 2012 to increase 10% to 15% sequentially to $27 million to $28 million. Built into this range, we expect our cable revenues to continue to increase on a quarter-over-quarter basis with the majority of the strength expected in DOCSIS 3.0 data and cable video server gateway applications on both an absolute and percentage of total revenue basis, accompanied by a general flatness across a range of our terrestrial operations.
We expect GAAP and non-GAAP gross profit percentage to be approximately flat to down modestly at 61% in the third quarter. And our gross profit percentage forecast could vary somewhat depending on the mix and other factors.
We continue to fund strategic development programs targeted to delivering top line growth, 2012 and beyond with a focus on increasing the operating leverage of the business. As such, we anticipate incremental tape-out related expenses and measured net headcount additions in the current quarter.
We expect GAAP operating expenses to be flat relative to the prior quarter at $17.5 million, reflective of lower export compliance-related expenses and lower accrued payroll items, offset by higher run rate expenses related to the Silicon Laboratories patent litigation and some tape-out related NRE and peak CAD tools usage in the quarter.
We expect Q3 2012 non-GAAP operating expenses will increase to $14 million, again, due to NRE and peak CAD tools usage, modest hiring in the quarter and the full effect of our annual merit increases implemented in the second quarter.
In summary, we are pleased to report strong sequential revenue growth along with soft -- strong top line guidance, accompanied by stabilizing gross margins and an OpEx model that's delivering increasing operating leverage and positive cash flow.
With that, I'd like to now open the call to questions. Operator?
