3 This specification can be used to calculate phase noise for any application. Use the formula ((Normalized Phase Noise Floor) + 10 log(fPFD) + 20 logN) to calculate
in-band phase noise performance as seen at the VCO output.
4 The PLL phase noise is composed of flicker (1/f) noise plus the normalized PLL noise floor. The formula for calculating the 1/f noise contribution at an RF frequency (fRF
and at an offset frequency (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™.

5 The phase noise performance is measured with a modified EV-ADF4159EB3Z evaluation board and the Rohde & Schwarz® FSUP signal source analyzer.
6 fREFIN = 100 MHz, fPFD = 100 MHz, offset frequency = 50 kHz, RFOUT = 12,002 MHz, N = 120.02, and loop bandwidth = 250 kHz.
