I'm not sure how to interpret the RF Input Sensitivity for the ADF4002 (I'm not a RF designer).
According to the datasheet the RF Input Sensitivity is -10 - 0dBm (referred to 50ohm).
We have a differential AC coupled driver (square wave) with 100ohm termination connected to ADF4002 RFinA and RFinB.
What is the maximum allowed voltage swing between RFinA and RFinB to fulfill the specification.
Is it sqrt(1m*10^(0dBm/10)*50) = sqrt(1mW*50ohm) = 224mV?
What happends if the 0dBm specification is violated?
