IMS-GNS Clock : IMS Clock Module with Multi GNSS Receiver for GPS, Galileo, GLONASS and BeiDou

This module is required for redundant clock module configurations and switches the synchronization signals from the selected clock module to the IMS backplane (most I/O modules use these backplane signals to generate their output signals).

A new feature offers a phase neutral switchover for LIU output cards, avoiding phase jumps for telecommunication signals (E1/T1). The RSC can be configured to automatically switch between the two clock modules based on their status but it is also possible to manually select the clock module using the selection switches.

IMS-PZF Clock : PZF (DCF77) Correlation Receiver (Eurocard)

By evaluating the pseudo-random sequence (PZF), which is part of the DCF77 signal in addition to the amplitude modulation, the PZF clock is capable to reproduce a time pattern in the range of microseconds. This allows generation of high precision pulses and an accurate adjustment of the main oscillator of the system. Besides various standard frequencies, the board provides a programmable frequency output. Additional features of IMS-PZF clock are pulses per second (PPS) and per minute (PPM) and IRIG timecode outputs.
