VCL-2145-SLV (IEEE-1588v2 Slave Clocks)
Product Overview
VCL-GPS IEEE-1588v2 PTP Grandmaster and Primary Reference Clock, NTP Server (IPv4 and IPv6), provides IRIG-B, 1PPS, NMEA, 1/5/10MHz, 2.048MHz, 2.048Mbits with SSM, 1.544Mbits GPS referenced clock outputs. OCXO and Rubidium Holdover Clock options available.
The VCL-GPS, IEEE-1588v2 PTP Grandmaster Receiver is specifically designed for the synchronization of 2G, 3G and LTE mobile telecommunications networks as well as backhaul wire-line SDH / SONET and Synchronous Ethernet networks. It may be also used by Railways, Airports (including air-traffic control), power generation and distribution companies and other utility companies who not only require a highly precise time-of-day and frequency synchronization locked to a GPS Reference but who also need to distribute highly precise time-of-day and frequency synchronization across all nodes of their networks.
The equipment conforms to and provides a G.811 / Stratum 1 quality synchronization (GPS locked) reference while providing multiple time (IRIG-B) and frequency outputs that are usually required by the users of such equipment.
The VCL-GPS, GPS Receiver is equipped with an integrated GPS receiver and a highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability holdover quality typical of an SSU in the eventuality of the GPS signal or its antenna failure.
