  • Patent number: 6621356
    Abstract: In order to shorten the transient recovery duration, the phase-locked loop has a voltage-controlled oscillator providing an oscillator signal to a first frequency divider. The first frequency divider divides the frequency of the oscillator signal, generates a first divider output signal therefrom, and passes it to a phase comparator during the transient recovery duration of the phase-locked loop. Furthermore, a unit is provided, which, after the transient recovery duration of the phase-looped loop, divides the frequency of the first divider output signal and passes it to the phase comparator. The phase comparator compares the first divider output signal with a first reference signal during the transient recovery duration. The phase comparator compares the divided divider output signal with a second reference signal after the transient recovery duration. The output of the phase comparator is connected to the voltage-controlled oscillator via a controllable charge pump.
