VCL-PTP-2112, PTP Slave Clock

PTP IEEE-1588v2 Slave Clock for ToD (Time of Day) and Frequency Synchronization

Product Overview

VCL-PTP-2112, PTP Slave Clock is a high precision, high reliability time and frequency synchronization solution which can be used to synchronize with an IEEE-1588v2 PTP Grandmaster to provide reference frequency and time-of-day synchronization across all nodes of a PTP network. Multiple 1PPS / IRIG-B Outputs are also provided to synchronize local clock (time-of-day) display units as well as RTUs to a central timing source with nanosecond accuracy.

The VCL-PTP-2112, PTP Slave Clock is specifically designed for the synchronization of 2G, 3G and LTE mobile telecommunications networks as well as 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 all nodes of their networks.

The VCL-PTP-2112, PTP Slave Clock is equipped highly accurate, low-noise OCXO which provides a high stability holdover that is typical of an SSU in the event of a failure of the transmission link.
