All clocks in a sync network must be referenced, or traceable, to a Primary Reference Source (PRS). Providing the highest level of time and/or frequency accuracy for telecom networking as required by international standards, Microsemi's PRS equipment is categorised by the source that is used to derive timing outputs: GPS, Cesium (atomick clock) or packet PRS (IEEE 1588 v2 PTP).The availability of precision time and frequency within the network assures the highest level of time and frequency accuracy throughout the network. This is enabled by advances in IEEE 1588 Precision Time Protocol, GPS and atomic clock technologies.


TimeCesium 4400

Based on the latest Cesium III technology, TimeCesium™ 4400 is an autonomous Primary Reference Source designed to generate superior, highly reliable Stratum 1 synchronisation signals for advanced telecom network services.
