CLKC
frequencies come from the same PLL but can have different
divider values.
In order to minimize PPM (Parts Per Million) error on the clock
outputs, a user should choose a crystal reference frequency
that is a common multiple of the desired PLL frequencies.
While this would be the ideal situation, this is not always the
case and the PLLs have high-resolution counters internally to
help minimize frequency deviation from the desired frequency.

PLL VCO frequencies are generated by the following
equation: F
VCO
= F
REF
* (P / Q)
Where F
REF
is the reference input frequency, P is the PLL
feedback divider and Q is the reference input divider.
A PLL is a feedback system where the VCO frequency divided
by P and reference frequency divided by Q are constantly
beingcomparedandtheVCOfrequencyisadjustedto achieve
a locked state.
Figure 1
is a simplified drawing of a PLL.
