Telecom Primary Reference Sources

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).
