Clock Module
The Clock module (23478272-xxx-0) provides an internal reference for measuring
the phase of the input signal. The CPU module locks the clock to the selected input
and maintains tracking with a variable control value. When the inputs are not
available, the clock enters the Holdover mode, and the frequency is maintained at
the last valid setting. The Clock module also supplies reference signals to the
Frame Generator module for all output signal generation. The front panel of the
Clock module is shown in
