The present invention relates to a delay control circuit and a method of controlling delay of an output signal generating based on an input signal, wherein a plurality of delayed replicas of a reference signal are generated with dedicated time delays with respect to the reference signal and are sampled at a predetermined timing defined by the input signal. One of the delayed replicas is selected based on the output of the sampling means, and the output signal is generated based on the selected replica. Thereby, a predetermined phase relationship can be generated even in cases where no strict phase relation is given between data and reference signal.
