ABSTRACT:
A timing control circuit to be used for a phase locked loop (PLL) wherein, a plurality of delay circuit elements capable of controlling the delay connected in series are used as a signal delay circuit, delay values of all the delay circuit elements can be changed at the same time with the delay control signals of the respective delay circuit elements being commonly connected, and the delay control signal is controlled so as to select the desired delay with the combination of a selecting circuit, a bi-directional shift register circuit, a phase detecting circuit, a shift control circuit, a delay control circuit so as to realize the wide range of timing control, thereby to provide a function of adjusting the delay of a signal delay circuit for effecting a timing control operation.
