Enhanced PRTC (eprtc)
Enhanced Primary Reference Time Clock
The TimeSource Enhanced PRTC (ePRTC) is designed to meet the newly consented ITU-T Recommendation G.8272.1 for enhanced Primary Reference Time Clocks and provides a unique solution to help protect telecom and mobile networks against GNSS vulnerabilities. Using an innovative approach to “generate time” by producing its own timescale which is driven by high performance Cesium frequency standards and aligned with GNSS time, the Time Source ePRTC delivers an autonomous, secure and fault tolerant reference for time, phase and frequency synchronization.
Mitigates Threat of GNSS Vulnerabilities
Meets the new ITU-T Recommendation G.8272.1
TU has recently consented Recommendation ITU-T G.8272.1 which specifies the requirements for enhanced Primary Reference Time Clocks (ePRTCs). This new recommendation describes more stringent output performance levels that will set the foundation for time, phase and frequency for many years to come. Also described in G.8272.1 is the requirement for an ePRTC to have a frequency input that can be fed with an autonomous primary reference clock. The new TimeSource ePRTC is designed and tested to meet this new industry standard.
Unites with the 5071A Cesium Frequency Standard
Microsemi unites the advantages of the TimeSource ePRTC with the world’s most widely adopted frequency standard for UTC generation, the 5071A Cesium frequency standard. The TimeSource ePRTC, can be purchased standalone or combined with one or two 5071A units to deliver a complete solution stack.
