Abstract
A technology capable of avoiding malfunction of a delay locked loop without generating a constant phase error in a delay locked loop circuit is provided. In a delay locked loop circuit, a control circuit is disposed in the outside of a delay locked loop, and in phase comparison of the delay locked loop, the control circuit outputs a control signal to the delay locked loop so that the relation in the phase comparison between a reference signal and an output signal is shifted by a set cycle.
