What Pericom Semiconductor does
Pericom Semiconductor Corporation, founded in 1990 and headquartered in San Jose, California, designed, developed, and marketed high-performance integrated circuits and frequency-control products. Its core technology centered on precision timing solutions: clock integrated circuits, crystal and crystal oscillators, and MEMS-based oscillator technology used to generate, distribute, and condition clock signals in electronic systems. The company served a horizontal customer base of electronics manufacturers across consumer, automotive, and industrial end-markets, with its components specified into computing, communications, and consumer-electronics applications for serial switching, clock distribution, and signal integrity functions.
Pericom's go-to-market was a fabless/IDM-style semiconductor model, selling reference designs and qualified timing components to OEMs and ODMs across its target segments. Distribution was through the manufacturer's representative and authorized-distributor channels typical of the analog/mixed-signal industry, with automotive-grade timing representing a distinct vertical under the portfolio. Co-founders Alex Chi-Ming Hui (CEO) and John Hui (SVP R&D) led the company for decades, and the organization employed 501-1,000 people at its established operating scale.
Pericom was publicly traded on NASDAQ under the ticker PSEM and was subsequently acquired by Diodes Incorporated, a publicly traded analog and discrete semiconductor company. Post-acquisition, Pericom operates as a brand/product line inside Diodes' timing category, retaining Clock ICs and Crystal and Crystal Oscillators product families and continuing to receive product investment under the broader Diodes portfolio that includes automotive timing, signal integrity ReDrivers, and isolation products.
