Using 50 Ω resistors to AV
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:
PN
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 (f
the normalized phase noise floor and flicker noise are modeled in ADIsimPLL.
