14 CLOCK SYSTEM
14.1
The internal CGC generates the system clocks LLC, LLC2
and the clock reference signal CREF. The internally
generated LFCO (triangular waveform) is multiplied by 4
via the analog PLL (including phase detector, loop filter,
VCO and frequency divider). The rectangular output
signals have a 50% duty factor.
