3 This figure can be used to calculate phase noise for any application. To calculate in-band phase noise performance as seen at the VCO output, use the following formula:
PNSYNTH = PNTOT − 10 log(fPFD) − 20 log N
where PNTOT is the measured in-band phase noise at the VCO output.
4 The PLL phase noise is composed of flicker (1/f) noise plus the normalized PLL noise floor. The flicker noise is specified at a 10 kHz offset and normalized to 1 GHz. The
formula for calculating the 1/f noise contribution at an RF frequency (fRF) and at a frequency offset (f) is given by PN = PN1_f + 10 log(10 kHz/f) + 20 log(fRF/1 GHz). Both
the normalized phase noise floor and flicker noise are modeled in ADIsimPLL.
