PHASE-LOCKED LOOP COMPRISING A PULSE GENERATOR, AND METHOD FOR OPERATING SAID PHASE-LOCKED LOOP

摘要

The invention relates to a phase-locked loop comprising a pulse generator. Said phase-locked loop is provided with a phase detector (23) for comparing a reference signal with an oscillator signal (FVCO'), and a detector output (23.3) for tapping a phase comparison signal (PVS). Said pulse generator (22) is used to produce a pulse-width-modulated pulse signal (PWL) and has a generator output (22.2) from which the pulse-width-modulated pulse signal (PWL) can be tapped. Furthermore, a selection unit (24) is provided, said unit being connected to the detector output (23.3) and the generator output (22.2) on the input side and being embodied in such a way that the phase comparison signal (PVS) or the pulse signal (PWL) can be selectively tapped from an output (62) of the selection unit (24) by means of a control signal (MC) which can be applied to a control input (60, 61) of the selection unit (24).
