Business Combinations [Abstract]
Acquisitions	Acquisitions On March 30, 2012, the Company acquired privately-held Multigig, Inc. (Multigig) of San Jose, California. The acquisition of Multigig is expected to enhance the Company’s clocking capabilities in stand-alone and embedded applications and strengthen the Company’s high speed signal processing solutions. The acquisition-date fair value of the consideration transferred totaled $26.8 million, which consisted of $24.2 million in initial cash payments at closing and an additional $2.6 million subject to an indemnification holdback that is payable within 15 months of the transaction date, which is included in accrued liabilities in the consolidated balance sheet as of November 3, 2012. The Company’s assessment of fair value of the tangible and intangible assets acquired and liabilities assumed was based on their estimated fair values at the date of acquisition, resulting in the recognition of $15.6 million of IPR&D, $1.1 million of developed technology, $7.0 million of goodwill and $3.1 million of net deferred tax assets. The goodwill recognized is attributable to future technologies that have yet to be determined as well as the assembled workforce of Multigig. Future technologies do not meet the criteria for recognition separately from goodwill because they are a part of future development and growth of the business. None of the goodwill is expected to be deductible for tax purposes. During the third quarter of fiscal 2012, the Company reduced this holdback amount by $0.1 million as a result of indemnification claims. During the fourth quarter of fiscal 2012, the Company finalized its purchase accounting for Multigig which resulted in adjustments of $0.4 million to deferred taxes and goodwill. In addition, the Company will be obligated to pay royalties to the Multigig employees on revenue recognized from the sale of certain Multigig products through the earlier of 5 years or the aggregate maximum payment of $1.0 million. Royalty payments to Multigig employees require post-acquisition services to be rendered and, as such, the Company will record these amounts as compensation expense in the related periods. As of November 3, 2012, no royalty payments have been made. The Company recognized $0.5 million of acquisition-related costs that were expensed in the second quarter of fiscal 2012, which were included in operating expenses in the consolidated statement of income. On June 9, 2011, the Company acquired privately-held Lyric Semiconductor, Inc. (Lyric) of Cambridge, Massachusetts. The acquisition of Lyric gives the Company the potential to achieve significant improvement in power efficiency in mixed signal processing. The acquisition-date fair value of the consideration transferred totaled $27.8 million, which consisted of $14.0 million in initial cash payments at closing and contingent consideration of up to $13.8 million. The contingent consideration arrangement requires additional cash payments to the former equity holders of Lyric upon the achievement of certain technological and product development milestones payable during the period from June 2011 through June 2016. The Company estimated the fair value of the contingent consideration arrangement utilizing the income approach. Changes in the fair value of the contingent consideration subsequent to the acquisition date primarily driven by assumptions pertaining to the achievement of the defined milestones will be recognized in operating income in the period of the estimated fair value change. As of November 3, 2012, the Company has paid $2.0 million in contingent consideration. The payment is reflected in the statements of cash flows as cash used in financing activities related to the liability recognized at fair value as of the acquisition date and cash provided by operating activities related to the fair value adjustments previously recognized in earnings. The Company’s assessment of the fair value of the tangible and intangible assets acquired and liabilities assumed was based on their estimated fair values at the date of acquisition, resulting in the recognition of $12.2 million of IPR&D, $18.9 million of goodwill and $3.3 million of net deferred tax liabilities. The goodwill recognized is attributable to future technologies that have yet to be determined as well as the assembled workforce of Lyric. Future technologies do not meet the criteria for recognition separately from goodwill because they are a part of future development and growth of the business. None of the goodwill is expected to be deductible for tax purposes. The fair value of the remaining contingent consideration was approximately $12.2 million as of November 3, 2012, of which $6.8 million is included in accrued liabilities and $5.4 million is included in other non-current liabilities in the consolidated balance sheet. In addition, the Company will be obligated to pay royalties to the former equity holders of Lyric on revenue recognized from the sale of Lyric products and licenses through the earlier of 20 years or the accrual of a maximum of $25.0 million. Royalty payments to Lyric employees require post-acquisition services to be rendered and, as such, the Company will record these amounts as compensation expense in the related periods. As of November 3, 2012, no royalty payments have been made. The Company recognized $0.2 million of acquisition-related costs that were expensed in the third quarter of fiscal 2011, which were included in operating expenses in the consolidated statement of income. The Company has not provided pro forma results of operations for Multigig and Lyric herein as they were not material to the Company on either an individual or an aggregate basis. The Company included the results of operations of each acquisition in its consolidated statement of income from the date of each acquisition.
