VCL-2750, IEEE-1588v2 PTP Slave (DIN Rail Version)

Get Data Sheet

VCL-2750, PTP (IEEE-1588v2) Slave Clock (DIN Rail Version) - synchronizes from a PTP Grandmaster to provide 1PPS, IRIG-B and NMEA Outputs with high stability OCXO holdover.

VCL-2750, PTP Slave Clock (DIN Rail Version) is a high precision, high reliability time and frequency synchronization solution which can be synchronized from a IEEE-1588v2 PTP Grandmaster to provide frequency and time-of-day synchronization across a PTP network with nanosecond accuracy. Multiple 1PPS / IRIG-B Outputs are provided to synchronize local clock (time-of-day) to IEDs, as well as RTUs to a central timing source.

The VCL-2750, PTP Slave Clock is specifically designed for providing synchronization in 2G/3G/4G, HetNet and LTE mobile telecommunications networks as well as in backhaul wire-line TDM Networks. It may be also used by Railways, Airports (including air-traffic control), Power generation and distribution companies and other Utility companies who need to distribute highly precise time-of-day and frequencies locked to a PTP Grandmaster (GPS) Reference across multiple nodes of their networks.

The VCL-2750, PTP Slave Clock is equipped with a highly accurate, low-noise OCXO which provides a high stability holdover that is typical of a Network SSU in the event of a failure of the transmission link.
