The CGM generates the crystal clock signal, CGMXCLK, which operates
at the frequency of the crystal. The CGM also generates the base clock
signal, CGMOUT, from which the system clocks are derived. CGMOUT
is based on either the crystal clock divided by two or the phase-locked
loop (PLL) clock, CGMVCLK, divided by two. The PLL is a frequency
generator designed for use with 1-MHz to 8-MHz crystals or ceramic
resonators. The PLL can generate an 8-MHz bus frequency without
using high frequency crystals.
Features of the CGM include:
•
•
•
•
•
Phase-Locked Loop with Output Frequency in Integer Multiples of
the Crystal Reference
Programmable Hardware Voltage-Controlled Oscillator (VCO) for
Low-Jitter Operation
Automatic Bandwidth Control Mode for Low-Jitter Operation
