GPS/GNSS Primary Reference Clock (PRC)
VCL offers a comprehensive range of GPS/GNSS Primary Reference Clocks compliant with ITU-T G.811 and featuring a 1+1 fully redundant architecture. These systems deliver Stratum-1 precise time and frequency synchronization for telecom, utilities, railways, airports, and mission-critical networks. Supporting IEEE-1588v2 PTP Grandmaster, NTP/SNTP, IRIG-B, 1PPS, NMEA-0183 (TOD - Time-Of-Day) and multiple frequency outputs (2.048 Mbps / 1.544 Mbps, 2.048MHz, 1/5/10MHz, 1PPS, 1PPM), they ensure accurate distribution of time-of-day and synchronization across all network nodes. All GPS clock outputs are phase-aligned and time-consistent, synchronized via internal CYP Sync. Advanced OCXO and Rubidium holdover options guarantee stability during GNSS outages.
