Microchip Technology recently announced the release of the TimeProvider 4500 v3 grandmaster clock (TP4500), designed to deliver sub-nanosecond accuracy for time distribution across 800 km long-haul optical transmission.
This innovative solution provides critical infrastructure operators with the missing link the industry has been waiting for in terms of complementary Positioning, Navigation and Timing (PNT). The TP4500 provides a resilient, terrestrial solution in the absence of GNSS for precise timing, alleviating physical obstruction, security and signal interference costs associated with GNSS-dependent deployments.
Most current deployments require GNSS at grandmaster sites, but the TP4500 enables highly resilient synchronisation without relying on GNSS. The TP4500 supports time reference provided by UTC(k) UTC time provided by national labs, and is the first grandmaster to offer a premium capability that delivers High Accuracy Time Transfer (HA-TT) to meet 5 nanoseconds time delay over 800 km, setting a new industry benchmark for accuracy.
Optimised for telecom, utilities, transportation, government, and defence, the TP4500 grandmaster ensures precise and resilient timing where it matters most. This latest version provides operators with a scalable solution for secure and reliable time distribution over long distances.
