COMMUNICATIONS VCL-2112
IEEE-1588v2 PTP Slave
Introduction: Application Diagram:
VCL-2112, IEEE-1588v2 PTP Slave Clock is a high precision,
high reliability time and frequency synchronization INPUT IEEE-1588v2 (PTP) – RJ45
solution which can be used to synchronize with an IEEE-
1+1 Power Supply
1588v2 PTP Grandmaster to provide frequency and time- VCL-2112-PTP 1588v2 SLAVE
(AC or/and DC)
of-day synchronization across all nodes of a PTP network.
OUTPUTS 2 x 1PPS / IRIG-B (2 Outputs) – BNC
Multiple 1PPS / IRIG-B Outputs are also provided to 1 x E1 – 2.048 Mbps / T1 – 1.544 Mbps – RJ45
synchronize local clock (time-of-day) display units as well 1 x 2.048 MHz – BNC
1 x 10 MHz – BNC
as RTUs to a central timing source with nanosecond 1 x NMEA 0183 ToD (Time-of-Day) Output – DB-9
