Clock Module
The RFD is not in the feedback loop of the PLL, so changing the RFD divisor does not affect PLL
operation.

Actual component values depend on crystal specifications.
The following subsections describe each major block of the PLL. Refer to
functional sub-blocks interact.
9.7.4.1
The PFD is a dual-latch phase-frequency detector. It compares both the phase and frequency of the
reference and feedback clocks. The reference clock comes from either the crystal oscillator or an external
clock source.
