A plurality of delay paths are connected in parallel between two synchronous operation circuits operating in synchronism with a clock signal CLK, and enable transmission of a signal. A delay detection unit detects the respective delay times of the plurality of delay paths, and a control unit selects one delay path from among the plurality of delay paths based on the detection results from the delay detection unit, and controls the blocking of signal transmission in the delay paths other than the selected one delay path.
