NOISE CHARACTERISTICS
In-Band Phase Noise of the Charge
Pump/Phase Frequency Detector
(In-Band Is Within the LBW of the PLL)
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)
At 500 kHz PFD Frequency

PLL Figure of Merit (FOM)

dBc/Hz
Reference slew rate > 0.25 V/ns; FOM + 10 log(fPFD) is an
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)

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