Cesium Atomic Clock Portfolio from Microsemi
Microsemi Corporation provides semiconductor solutions differentiated by power, security, reliability and performance. Recently they have completed the certification of its Cesium clocks portfolio to be compliant with the new G.811.1 recommendation. This new standard raises the bar for frequency accuracy by an order of magnitude from 1x10E-11 to 1x10E-12.
All clocks in a network must be referenced to a Primary Reference Source (PRS). Microsemi’s Cesium frequency standards 5071A, TimeCesium 4400 and TimeCesium 4500 with ePRC compliance provide the highest level of autonomous frequency accuracy. They are suitable for PRS deployment in telecom networks as required by international standards.
Its enhanced primary reference Clock Standards for precision time raises the performance bar for atomic standards.
According to the data from the International Bureau of Weights and Measures (BIPM), more than 99 percent of the Cesium clocks deployed for the world’s time keeping and national time standards are being driven by Microsemi’s Cesium products.
Microsemi has introduced a number of solutions providing customers within the communications, power utilities, public safety, data center and government network markets with a secure and resilient timing environment, reducing dependency on Global Navigation Satellite System (GNSS). The foundation of these solutions are Microsemi’s Cesium atomic clocks, which provide an “autonomous frequency reference” utilising enhanced timescale algorithms.
Ramki Ramakrishnan, Director of Product Management, Microsemi shared, “As next-generation networks increasingly rely more on accurate time to achieve higher transport speeds and increased reliability, the pervasive use of GNSS technology as a time reference has become a major concern because of vulnerabilities to threats such as jamming and spoofing. As a result, use of Cesium technology as the primary reference clock has become critical.
Cesium clock technology from Microsemi is utilized in GPS satellites, both in space and ground stations and underpin the rapidly growing GPS market. The GPS receiver market alone is poised to grow at approximately 16 percent between 2017-2021 according to Orbis Research, supporting applications in communications, enterprise, defense, automotive and public utility markets with a robust holdover technology.
