Phase-locked loop with output frequency in integer multiples of an
integer dividend of the crystal reference
Low-frequency crystal operation with low-power operation and
high-output frequency resolution
Programmable prescaler for power-of-two increases in frequency
Programmable hardware voltage-controlled oscillator (VCO) for
low-jitter operation
Automatic bandwidth control mode for low-jitter operation
Automatic frequency lock detector
CPU interrupt on entry or exit from locked condition
Configuration register bit to allow oscillator operation during stop
mode
Oscillator module — The oscillator module generates the constant
reference frequency clock, CGMRCLK (buffered CGMXCLK).
Phase-locked loop (PLL) — The PLL generates the
programmable VCO frequency clock, CGMVCLK, and the divided,
CGMPCLK. The CGMPCLK is one of the reference clocks to the
base clock selector circuit.
Base clock selector circuit — This software-controlled circuit
selects the one of three clocks as the base clock, CGMOUT:
CGMXCLK, CGMXCLK divided by two, or CGMPCLK divided by
two.
