1.1Features

The Clock Generator Module (PMC-CGM) is a PMC module which is either available together with the Emerson ATCA-F103 switch or as part of an accessory kit. It can only be used in conjunction with the ARTM-F103-STX.

The PMC-CGM is delivered with payload software which lets you configure and monitor the clock synchronization via SNMPv2 and Management Information Bases (MIBs). You may use the software as an interface to write a higher-level clock manager software.

The PMC-CGM serves the following purposes:

zSynchronizes to a reference clock (line card clock CLK3, aka. REFA/REFB or external E1/T1 clock) and provides a system clock (CLK1/CLK2) in an AdvancedTCA chassis and to up to two extension shelves.

zActs as temporary stand-alone clock source if all reference clocks failed while maintaining clock phase and frequency as long as possible ("holdover mode").

This is accomplished by measuring the reference clock against a high-precision oscillator and calculating the frequency/phase offset to be applied when the reference clock fails.

The hardware/firmware is designed so that two clock modules form a protection (master/slave) pair. If the master module fails, the slave module takes over seamlessly without disturbing the system clocks.

For a PMC-CGM support on the ATCA-F103, the following software versions (or higher) are required on the ATCA-F103:

zApplication: 4.0.629

zIPMI firmware: 1.03.082

zBootloader: 4.0.629

For more details on the clocking concept used in your system refer to the Centellis CO 31kX Installation and Use manual.
