Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the fair value of the underlying net tangible and intangible assets. Goodwill is not amortized, but is instead tested for impairment annually or more frequently if certain indicators of impairment are present. We do not expect goodwill impairment to be tax deductible for income tax purposes. No impairment charges relating to goodwill were recorded for the first six months of fiscal 2017 or fiscal 2016 as no indicators of impairment were present. In the first quarter of 2016, we finalized our valuation and allocation of purchase price consideration related to the acquisition of Silicon Image, Inc. ("Silicon Image") resulting in $2.1 million of additional long-term liabilities related to an uncertain tax position with an equivalent revision to Goodwill, which is reflected in the Consolidated Balance Sheets for the period ended December 31, 2016. The goodwill balance of approximately $269.8 million at both July 1, 2017 and December 31, 2016 is comprised of approximately $44.8 million from prior acquisitions combined with the approximately $237.6 million from the acquisition of Silicon Image, reduced by the fiscal 2015 goodwill impairment charge of approximately $12.7 million.
