description A frequency locked loop for generating a clock signal, comprising: a controllable oscillator configured to, in dependence on a control signal, generate an oscillator signal having an oscillator signal frequency; a frequency divider coupled to the controllable oscillator configured to reduce the oscillator signal frequency to form a divided oscillator signal frequency; and a frequency detector coupled to the frequency divider and configured to generate the control signal in dependence on a reference signal frequency; wherein the frequency divider comprises a first counter and a second counter, the first counter configured to be clocked by the oscillator signal and to produce a first counter output signal, and the second counter configured to be clocked by the first counter output signal.
