Symmetricom, Inc. (NASDAQ: SYMM) (now acquired by Microsemi) develops, manufactures, and supplies timekeeping technology to customers in industry and government worldwide that require extremely precise synchronization. Symmetricom products support today’s precise timing standards, including GPS-based timing, IEEE 1588 (PTP), Network Time Protocol (NTP), Synchronous Ethernet and Data Over Cable Service Interface Specifications (DOCSIS®) timing.

Products include 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.

Symmetricom is one of the only two world’s commercial supplier of cesium atomic standards (atomic clocks) - the other one is Oscilloquartz, in Switzerland. By weighted average, Symmetricom atomic clocks contribute over 90% of UTC (Coordinated Universal Time, the world time standard). The BIPM (International Bureau of Weights and Measures) calculates UTC by averaging the combined contributions of the national laboratories of its member countries.

In addition to its products, Symmetricom also offers various lifecycle services including: engineering and installation, operations and support programs, maintenance, training and certification programs and professional development courses as well as consulting and other professional services to support customers of its product lines.

Symmetricom is headquartered in San Jose, California with research and development centers in Boulder, Colorado; Beverly, Massachusetts; Tuscaloosa, Alabama; and Beijing, China.


Symmetricom was acquired by Microsemi in Oct 2013
