Microchip's TimeProvider 4500 v3 Sets New Benchmark: Sub-Nanosecond Accuracy Across 800 km Without GNSS
Breakthrough Solution Enables Sub-Nanosecond Time Transfer Over Long-Haul Optical Networks
Critical infrastructure operators are under increasing pressure to ensure uninterrupted, ultra-precise timing—even if Global Navigation Satellite Systems (GNSS) are disrupted. In a significant move, Microchip Technology has launched the TimeProvider® 4500 v3 grandmaster clock (TP4500), which delivers sub-nanosecond accuracy in time transfer across distances of up to 800 kilometers using terrestrial, long-haul optical networks.
Industry-First: Achieving 5 ns Delay Over 800 km Sets New Standard for Accuracy
The TP4500 achieves a breakthrough by maintaining less than 5 nanoseconds (ns) time delay over 800 km—setting a new industry standard and directly answering global demand for robust timing infrastructure. By eliminating dependency on GNSS at each synchronization node, the solution offers significant security and cost advantages, addressing physical obstruction, interference, and operational vulnerabilities.
Designed for Modern Demands: Versatile, Carrier-Grade Timing Across Critical Sectors
The TimeProvider 4500 v3 isn't just an incremental update—it's a premium platform tailored for the future of network infrastructure. It enables network operators to deploy a carrier-grade, standards-based timing network known as virtual Primary Reference Time Clock (vPRTC). This solution is adaptable for telecom, utilities, government, defense, and transportation, ensuring uninterrupted precision, even during GNSS outages.
| Key Feature | Benefit |
|---|---|
| Sub-nanosecond Accuracy (=5 ns delay up to 800 km) | Enables extremely precise time synchronization over vast distances |
| GNSS Independence | Reduces vulnerability to satellite outages and jamming |
| Supports UTC(k) Time from National Labs | Ensures industry-standard reference and compatibility |
| Integration with Existing Networks | Seamless deployment using Ethernet and optical infrastructure |
| Carrier-Grade Virtual PRTC (vPRTC) | Provides end-to-end timing accuracy across critical infrastructure |
| Exclusive High-Accuracy Time Transfer (HA-TT) | Industry's first to meet stringent ITU-T G.8271.1/Y.1366.1 requirements |
Future-Ready: Built to Support New Standards and Resilience Requirements
This platform is also a key stepping stone toward supporting the upcoming ITU-T G.8272.2 standard for coherent network reference time clock (cnPRTC), promising highly robust network-wide timekeeping—crucial for 5G and mission-critical applications. Microchip’s integration of proprietary FPGA and synthesizer technology further sets the TP4500 apart for accuracy and scalability.
Takeaway: Why This Matters for Critical Infrastructure Operators
The release of the TP4500 signals a meaningful evolution in how operators secure timing resilience in the face of increasingly complex risks. By offering unmatched accuracy without the need for constant GNSS availability, the solution empowers organizations to protect against outages and maintain service-level agreements—particularly where timing errors can have wide-reaching operational and financial impacts.
