Microchip Technology announced today the release of its TimeProvider 4500 v3 grandmaster clock, a terrestrial timing solution that delivers sub‑nanosecond accuracy across long‑haul optical networks. The device is aimed at critical‑infrastructure operators—including telecom, utilities, transportation, government, and defense—who require resilient, satellite‑independent time distribution.
The TP4500 v3 achieves a 5 nanosecond time delay over 800 km, equivalent to an average of 500 picoseconds per node for a 10‑node network. It is the first grandmaster clock to provide high‑accuracy time transfer (HA‑TT) as defined by ITU‑T G.8271.1/Y.1366.1, supports UTC(k) time from national labs, and operates without reliance on Global Navigation Satellite Systems (GNSS).
Designed as part of Microchip’s IEEE‑1588 Precision Time Protocol portfolio, the TP4500 v3 offers a carrier‑grade, standards‑based architecture that can be integrated into virtual PRTC (vPRTC) networks. The solution positions Microchip to meet the ITU‑T G.8272.2 cnPRTC standard, ensuring highly accurate, resilient timekeeping throughout telecom and critical‑infrastructure networks even during GNSS outages.
The TimeProvider 4500 v3 is available for purchase in production quantities. Customers can contact a Microchip sales representative or an authorized distributor for pricing and availability details.
