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
20log(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 + 10log (fPFD) is an approxi-
mation 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 20log(N)

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.
