Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. The information included herein contains all normal recurring accruals and adjustments which, in the opinion of management, are necessary to present fairly Silicon Laboratories Inc.’s (the “Company”) financial position, results of its operations, comprehensive loss, stockholders’ equity, and cash flows. The Condensed Consolidated Balance Sheet as of December 28, 2024 was derived from the Company’s audited Consolidated Financial Statements. All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated results of operations for the three and six months ended July 5, 2025 are not necessarily indicative of the results to be expected for the full year. These Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto for the year ended December 28, 2024, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 4, 2025. The Company prepares financial statements on a 52- or 53-week fiscal year that ends on the Saturday closest to December 31. Fiscal 2025 will have 53 weeks with the extra week occurring in the first quarter of the year. Fiscal 2024 had 52 weeks. In a 52-week year, each fiscal quarter consists of 13 weeks. 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. Among the significant estimates affecting the financial statements are those related to inventories, goodwill, acquired intangible assets, other long-lived assets, revenue recognition, stock-based compensation, and income taxes. Actual results could differ from those estimates, and such differences could be material to the financial statements. The Company periodically reviews the assumptions used in its financial statement estimates. Recent Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740)—Improvements to Income Tax Disclosures. This ASU requires that reporting entities disclose specific categories in the effective tax rate reconciliation as well as information about income taxes paid. The authoritative guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. As the requirements of this ASU are disclosure-related, the adoption will not have an impact on the Company’s consolidated financial position and results of operations. The Company is currently evaluating the impact of this update on its income tax disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). This ASU requires that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The prescribed categories include purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depletion. This authoritative guidance is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effect of this new guidance on its consolidated financial statements.
