Centellax became part of Microsemi Corporation in September 2014, and the business now operates under Microsemi, a subsidiary of Microchip Technology Inc. Based in Aliso Viejo, California, Microsemi serves the semiconductor market with an integrated suite of products and solutions for communications, defense and security, aerospace, and industrial sectors. The offerings span timing and synchronization, power management, analog mixed-signal, and related technologies intended for high-reliability applications. Its customer base includes defense, aerospace, communications, and industrial users that require precise timing, resilient performance, and hardened or secure components for mission-critical systems.
