ABSTRACT:
A frequency synthesizer (51) arranged in a phase locked loop fashion to provide an output signal with a preselected frequency within a controlled lock time from a voltage controlled oscillator (51), having: a phase detector (55) with a controllable gain, that provides an error signal proportional to the controllable gain and corresponding to a phase difference between a reference signal and a feedback signal, an adapt circuit (121) for setting the controllable gain to an adapt value (205), and a tracking circuit (123) for setting the controllable gain to a tracking value (207) by adjusting the controllable gain in a predetermined and controlled fashion from the adapt value (205) to the tracking value (207).
