Microsemi SyncServer S650

Frequency Standard

The Microchip SyncServer S650 is a network time and frequency standard that provides time accuracy better than 15 ns RMS to UTC through GNSS. It delivers frequency accuracy better than 1 × 10⁻¹² when locked to GPS and supports 5 MHz 10 MHz and 1PPS timing outputs through modular I/O. The system supports high‑throughput NTP operation at 10 000 requests per second using hardware time stamping. Operation is specified over a temperature range of −20 °C to 65 °C in a 1U rack‑mount chassis.
