Governments throughout the globe are requesting crucial infrastructure operators to undertake further time sources alongside GNSS to boost resilience and reliability, guaranteeing uninterrupted operations within the face of potential disruptions or service limitations. Microchip Know-how introduced the discharge of the TimeProvider 4500 v3 grandmaster clock (TP4500) designed to ship sub-nanosecond accuracy for time distribution throughout 800 km long-haul optical transmission.
This progressive answer supplies crucial infrastructure operators with the lacking hyperlink the business has been ready for when it comes to complementary Positioning, Navigation and Timing (PNT). The TP4500 supplies a resilient, terrestrial answer within the absence of International Navigation Satellite tv for pc Techniques (GNSS) for exact timing, assuaging bodily obstruction, safety and sign interference prices related to GNSS-dependent deployments.
Most present deployments require GNSS at grandmaster websites, however the TP4500 allows extremely resilient synchronization with out counting on GNSS. The TP4500 helps time reference offered by UTC(okay) UTC time offered by nationwide labs, and is the primary grandmaster to supply a premium functionality that delivers Excessive Accuracy Time Switch (HA-TT) as outlined by ITU-T G.8271.1/Y.1366.1 (01/2024) to satisfy 5 nanoseconds (ns) time delay over 800 km (equating to 500 picoseconds (ps) common per node, assuming 10 nodes), setting a brand new business benchmark for accuracy.
The TP4500 system could be configured with a number of operation modes to type an end-to-end structure often known as digital PRTC (vPRTC), able to delivering PRTC accuracy over a long-distance optical community. vPRTC is a carrier-grade structure for terrestrial distribution of HA-TT, which has been extensively deployed in operator networks all through the world. HA-TT is a confirmed and cost-effective strategy, versus different different PNT options that don’t have any huge adoption into crucial infrastructure networks thus far, have low Know-how Readiness Ranges (TRL) and are nonetheless depending on GNSS as the final word supply of time.
“The TimeProvider 4500 v3 grandmaster is a breakthrough answer that empowers operators to deploy a terrestrial, standards-based timing community with unprecedented accuracy and resilience,” mentioned Randy Brudzinski, company vp of Microchip’s frequency and time techniques enterprise unit at Microchip. “This innovation displays Microchip’s dedication to delivering probably the most superior and dependable timing options for the world’s most important companies.”
TimeProvider 4500 v3 is a key steppingstone in the direction of help of the ITU-T G.8272.2 normal, which defines a coherent community reference time clock (cnPRTC) in modification 2 (2024). An cnPRTC structure ensures extremely correct, resilient, and strong timekeeping all through a telecom community. This permits secure, network-wide ePRTC time accuracy, even during times of regional or network-wide GNSS unavailability or different failures and interruptions.
Key options of the TimeProvider 4500 v3 collection:
- Sub-nanosecond accuracy: Delivers 5 ns time delay over lengthy distances as much as 800 km Terrestrial different to GNSS: Permits crucial infrastructure to function with resilient synchronization mechanisms unbiased of GNSS
- Seamless integration: Requirements-based terrestrial community for time switch, simply built-in with off-the-shelf small form-factor pluggable and present Ethernet and optical deployments
- Unique functionality: Premium software program options out there solely on the TP4500 v3, integrating Microchip’s PolarFire FPGA and Azurite synthesizer for unmatched precision
Optimized for telecom, utilities, transportation, authorities, and protection, the TP4500 grandmaster ensures exact and resilient timing the place it issues most. This newest model supplies operators with a scalable answer for safe and dependable time distribution over lengthy distances.
