1 AC coupling ensures AVDD/2 bias.
2 TA = 25°C; AVDD = DVDD = 3.3 V; prescaler = 8/9; fREFIN = 100 MHz; fPFD = 26 MHz; fRF = 1.7422 GHz.
3 Using a tuned load.
4 The synthesizer 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 N divider
value) and 10 log FPFD. PNSYNTH = PNTOT − 10logFPFD − 20logN.
5 The PLL phase noise is composed of 1/f (flicker) noise plus the normalized PLL noise floor. The formula for calculating the 1/f noise contribution at an RF frequency (FRF)
and at a frequency offset (f) is given by PN = P1_f + 10log(10 kHz/f) + 20log(FRF/1 GHz). Both the normalized phase noise floor and flicker noise are modeled in ADIsimPLL.
