ADF4002 Analog Lock Detect Design

Question asked by Adom on Jul 12, 2015

Please can anyone help me with a relationship between the allowable frequency deviation of a carrier and the pulses of the lock detect pin. I am designing an fm transmitter which would be modulated to allow +/-150KHz frequency drift from the carrier. What I want to do is detect greater frequency deviations than the above as a true out of lock condition in order not to confuse modulation of the carrier with an out of lock condition for my application.
