Abstract
A delay locked loop has a filter in order to set the delay time of a delay path in a manner dependent on the phase difference of input and output clock signals. The phase difference is ascertained by a phase detector. An additional control circuit determines the number of drive pulses of the filter and additionally controls the number of effective counter stages of a counter that forms the filter. The transient recovery time of the delay locked loop is thereby reduced.
