The AMC003 provides an accurate local clock frequency to a μTCA/ATCA system which is derived from a GPS 1PPS signal. The local oscillator is disciplined to provide the desired clock frequency and is constantly monitored and adjusted to account for oscillator drift and aging. An internal 1PPS generated signal is also provided which is phase aligned to the reference 1PPS signal. The re-generated 1PPS signal remains present even during holdover when the 1PPS would otherwise be unavailable from the GPS receiver.

A Stratum 3 VCTCXO is used to provide excellent holdover stability. Front panel indicators clearly show the status of the system including the presence and validity of the reference 1PPS, the frequency lock status, and the phase lock status. The module has a serial port in the front that enables advanced configuration and monitoring support. Locking/holdover status is also available via IPMI sensors.
