Symmetricom

Symmetricom, Inc. was an American company specialized in high precision timekeeping technology, acquired by Microsemi in 2013 for $230 million, which subsequently became part of Microchip Technologies Inc. Symmetricom developed products including hydrogen masers, rubidium and cesium atomic standards, temperature and oven controlled crystal oscillators, miniature and chip scale atomic clocks, network time servers, network sync management systems, cable timekeeping solutions, telecom synchronization supply units (SSUs), and timing test sets. The company launched the first commercial Chip Scale Atomic Clock (CSAC) model SA.45s in 2011, with over 100,000 units sold. The CSAC provides wide operating temperatures, fast warm-up/atomic-lock, and superior frequency stability in extreme environments. Symmetricom’s innovations supported quantum computing applications requiring ultra-precise timing synchronization. Now operated under Microchip Technology, the timing solutions serve aerospace, defense, communications, and quantum computing industries.

2025 Developments: The company continues to advance its quantum hardware capabilities throughout 2025. Ongoing research and development efforts focus on improving qubit performance and scalability. The organization maintains active collaboration with research institutions and industry partners.
