Symmetricom, Inc. was a U.S.-based enterprise focused on advanced precision timekeeping technologies. Its offerings encompassed essential timing protocols such as GPS timing, IEEE 1588 (PTP), Network Time Protocol (NTP), Synchronous Ethernet, and DOCSIS synchronization.
Products
The company’s range of products featured hydrogen masers, atomic standards including rubidium and cesium, temperature- and oven controlled crystal oscillators, compact and chip-scale atomic clock devices, network time servers, systems for network synchronization management, cable-based timing solutions, telecom synchronization supply units (SSUs), as well as timing measurement instruments.
Symmetricom was one of only two worldwide commercial manufacturers of cesium atomic clocks, the other being the Swiss firm Oscilloquartz. The atomic clocks produced by Symmetricom accounted for more than 90% of the weighted average used in determining UTC (Coordinated Universal Time), the global time standard overseen by the BIPM (International Bureau of Weights and Measures).
History
With its main office located in San Jose, California, Symmetricom maintained research and development facilities in Boulder, Colorado, Beverly, Massachusetts, Tuscaloosa, Alabama, and Beijing, China.
In 2013, Symmetricom was acquired by Microsemi in a transaction valued at $230 million. Later, in 2018, Microsemi itself became part of Microchip through acquisition.
