REFIN and REFIN self-bias points are offset slightly to avoid chatter on an open input condition.
For reliable operation of the digital lock detect, the period of the PFD frequency must be greater than the unlock-after-lock time.

Register 0x019: R, Bits[5:3]; N, Bits[2:0]; see Table 54
The PLL in-band phase noise floor is estimated by measuring
the in-band phase noise at the output of the VCO and
subtracting 20 log(N) (where N is the value of the N divider)
Reference slew rate > 0.25 V/ns; FOM + 10 log(f
approximation of the PFD/CP in-band phase noise (in the flat
region) inside the PLL loop bandwidth; when running closed
loop, the phase noise, as observed at the VCO output, is
increased by 20 log(N)
Signal available at LD, STATUS, and REFMON pins
when selected by appropriate register settings
