NOISE CHARACTERISTICS

In-Band Phase Noise of the Charge

Pump/Phase Frequency Detector

(In-Band Means 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)

@ 500 kHz PFD Frequency

−165

dBc/Hz

@ 1 MHz PFD Frequency

−162

dBc/Hz

@ 10 MHz PFD Frequency

−151

dBc/Hz

@ 50 MHz PFD Frequency

−143

dBc/Hz

PLL Figure of Merit (FOM)

−220

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)
