Phase-locked loop with short transient recovery duration and small interference signal component

A phase-locked loop, comprising:

• a voltage-controlled oscillator for generating an oscillator signal having a frequency;
• a controllable charge pump having an output connected to said voltage-controlled oscillator;
• a phase comparator having an output connected to said controllable charge pump;
• a first frequency divider which, during a transient recovery duration, generates a first divider output signal by dividing the frequency of the oscillator signal and provides the first divider output signal to said phase comparator, the first divider output signal having a frequency;
• a unit which, after the transient recovery duration, divides the frequency of the first divider output signal to obtain a divided first divider output signal and provides the divided first divider output signal to said phase comparator;
• and
• an accumulator for holding a value, said first frequency divider connected to said accumulator;
• said first frequency divider depending on the value held in said accumulator, dividing the frequency of the oscillator signal by a value selected from the group consisting of a first value and a second value;
• said phase comparator comparing the first divider output signal with a first reference signal during the transient recovery duration;
• and
• said phase comparator comparing the divided first divider output signal with a second reference signal after the transient recovery duration.
