For measurements that require RF input, RF input power is -10dBm unless otherwise specified.
For two-tone measurements, tone separation is 17MHz.
Output power, spurs, and harmonics can vary based on board layout and components.
For lower VCO frequencies, the N divider minimum value can limit the phase detector frequency.
The PLL noise contribution is measured using a clean reference and a wide loop bandwidth and is composed into flicker and flat components. PLLFLAT = PLLFOM + 20log(FVCO / FPD) + 10log(FPD / 1Hz). PLLFLICKER (offset) = PLLFLICKER_NORM + 20log(FVCO / 1GHz) - 10log(offset frequency / 10kHz). Once these two components are found, the total PLL noise can be calculated as PLLNOISE = 10log(10PLLFLAT / 10 + 10PLLFLICKER / 10).
See Application and Implementation for more details on the different VCO calibration modes.
