Abstract
A DLL circuit () includes a phase delay circuit (), a selection circuit (), a detection circuit (), and a clock stop circuit (). The phase delay circuit () generates a plurality of delayed signals having different phases according to a clock signal. The selection circuit () selects one of the plurality of delayed signals as an output signal according to a setting signal. The detection circuit () detects a timing of switching the setting signal. The clock stop circuit () stops input of the clock signal to the phase delay circuit () for a predetermined period including the timing detected by the detection circuit ().
