Segment Reporting [Abstract]  
Segment Information Segment Information
The Company's Chief Executive Officer functions as the chief operating decision maker ("CODM"). The CODM makes operating decisions and assesses performance based on the net sales and gross profit of the Company's major product lines, which represent its operating segments, to allocate resources (including employees, property, and financial or capital resources) for each segment predominantly in the annual budget and forecasting process. The Company currently has three operating segments—Signal Integrity ("SIP"), Analog Mixed Signal and Wireless ("AMW"), and IoT Systems and Connectivity ("ISC")—that represent three separate reportable segments. The SIP reportable segment consists of a portfolio of optical and copper data communications and video transport products used in a wide variety of infrastructure and industrial applications. The AMW reportable segment provides infrastructure, industrial and high-end customers with high-performance protection devices and a portfolio of specialized radio frequency products. The SIP and AMW reportable segments together constitute our Semiconductor Products business. The ISC reportable segment provides industrial customers with an IoT solutions portfolio that includes a wide range of modules, gateways, routers, and connected services.
The Company’s assets are commingled among the various operating segments and the CODM does not use asset information in making operating decisions or assessing performance. Therefore, the Company has not included asset information by reportable segment in the segment disclosures below.
The Company adopted the provisions of ASU 2023-07 for the year ended January 26, 2025, on a retrospective basis and included enhanced disclosures relating to its reportable segments.
Net sales and gross profit by reportable segment were as follows:
