Accounting Policies [Abstract]
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassification	Certain prior period balances have been reclassified to conform to the current period’s presentation. These reclassifications did not have a material impact on previously reported financial statements.
Recent Accounting Pronouncements	In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-06, Accounting for Convertible Instruments in an Entity’s Own Equity, which simplifies the accounting for convertible instruments and contracts on an entity’s own equity. The Company adopted ASU 2020-06 effective on January 1, 2022, using the modified retrospective method. Among other changes, ASU 2020-06 removes from U.S. GAAP the liability and equity separation model for convertible instruments with a cash conversion feature. As a result, the Company no longer separately presents in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature is no longer amortized into income as interest expense over the life of the instrument.
Segment Information	Operating segments are defined as components of an enterprise that engage in business activities for which separate financial information is available and evaluated regularly by the Company’s Chief Operating Decision Maker (the “CODM”), in deciding how to allocate resources and assess performance. The Company’s CODM is its Chief Executive Officer. Based on the Company’s internal reporting structure, the Company consists of two operating segments: Video and Broadband. During the third quarter of fiscal 2022, the Company’s Cable Access segment was renamed the Broadband segment to reflect a broader strategic view of the category. There has been no change to the composition of the segment; therefore, no prior periods were restated. The operating segments were determined based on the nature of the products offered.
Indemnification	The Company is obligated to indemnify its officers and the members of its Board of Directors pursuant to its bylaws and contractual indemnity agreements. The Company also indemnifies some of its suppliers and most of its customers for specified intellectual property matters pursuant to certain contractual arrangements, subject to certain limitations. The scope of these indemnities varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorneys’ fees).
