For More Information On This Product,
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
Crystal oscillator circuit — The crystal oscillator circuit generates
the constant crystal frequency clock, CGMXCLK.
Phase-locked loop (PLL) — The PLL generates the
programmable VCO frequency clock, CGMVCLK.
Base clock selector circuit — This software-controlled circuit
selects either CGMXCLK divided by two or the VCO clock,
CGMVCLK, divided by two as the base clock, CGMOUT. The SIM
derives the system clocks from either CGMOUT or CGMXCLK.
