Telecom Primary Reference Sources


The highest level of time and frequency accuracy throughout your network

All clocks in a synchronization network must be referenced, or traceable, to a Primary Reference Source (PRS). Microsemi’s GPS Primary Reference Sources, also known as "master clocks," provide the highest level of time and/or frequency accuracy for telecom networking as required by international standards. Our wide variety of PRS offerings are categorized by the source that is used to derive the timing outputs: GPS (Global Positioning System), Cesium (atomic clock), or Packet PRS (IEEE 1588v2 PTP). Advances in IEEE 1588 Precision Time Protocol, GPS and atomic clock technologies have enabled the availability of precision time and frequency within the network. This assures the highest level of time and frequency accuracy throughout the network.
