NOTE:
NOTE:
NOTE:
The following paragraphs describe the CGMC I/O signals.
The OSC1 pin is an input to the crystal oscillator amplifier.
The OSC2 pin is the output of the crystal oscillator inverting amplifier.
The CGMXFC pin is required by the loop filter to filter out phase
corrections. An external filter network is connected to this pin. (See
Figure
To prevent noise problems, the filter network should be placed as close
to the CGMXFC pin as possible, with minimum routing distances and no
routing of other signals across the network.
