Segment Reporting [Abstract] |
Segment Information | Segment Information The Company's CEO functions as the chief operating decision maker ("CODM"). The CODM makes operating decisions and assesses performance based on the Company's major product lines, which represent its operating segments. The Company has three operating segments—Signal Integrity, Wireless and Sensing, and Protection—that have similar economic characteristics and have been aggregated into one reportable segment identified as the "Semiconductor Products Group." 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 segment in the segment disclosures below. Net sales by reportable segment were as follows:
