摘要：
The phase-locked loop has a pulse generator has a phase detector which is intended to compare a reference signal with an oscillator signal, and a detector output for tapping off a phase comparison signal. The pulse generator is used to produce a pulse-width-modulated pulse signal and has a generator output, from which the pulse-width-modulated pulse signal is tapped off. A selection unit is furthermore provided and is connected, on the input side, to the detector output and to the generator output, and is designed in such a manner that either the phase comparison signal or the pulse signal can be tapped off from an output of the selection unit using a control signal applied to a control input of the selection unit.
