Abstract

The invention concerns a frequency locked loop comprising: a digitally controlled oscillator () configured to generate a frequency signal (F); a frequency counter () configured to generate an estimate (f_EST) of the frequency of the frequency signal based on a reference clock signal (CLK_REF); and a controller () configured to generate a digital control signal (C_FREQ) for controlling the digitally controlled oscillator based on the estimated frequency, wherein the controller is clocked by a further clock signal (CLK) having a variable frequency, and the controller is configured to generate a trigger signal (AUTO_CLEAR) for triggering a counting phase of the frequency counter.
