VCL-2750, IEEE-1588v2 PTP Slave / PTP to IRIG-B Converter


VCL-2750, PTP Slave Clock (DIN Rail Version) / PTP to IRIG-B Converter 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 / PTP to IRIG-B Converter 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.
