A circuit configuration includes a controllable oscillator issuing an output signal. A phase detector is acted upon by a reference signal and by the output signal of the oscillator. A first charge pump is controllable by the phase detector and has an input connected to the phase detector and an output. A loop filter is connected between the first charge pump and the oscillator for triggering the oscillator. A second charge pump is connected parallel to the output of the first charge pump.
