PLL2_N: PLL2_N Counter
The PLL2_N Counter is 18 bits wide. It divides the output of the VCO Divider and is connected to the PLL2
Phase Detector. Each time the PLL2_N Counter value is updated via the uWire interface, an internal algorithm is
triggered that optimizes the VCO performance.

VCO_DIV: PLL2 VCO Divide Register
A divider is provided on the output of the PLL2 VCO to enable a wide range of output clock frequencies. The
output of this divider is placed on the input path for the clock distribution section, which feeds each of the
individual clock channels. The divider provides integer divide ratios from 2 to 8.
