Abstract
A control circuit includes a control unit, a delay line unit, and a detection unit. The delay line unit delays an input clock signal based on the delay amount and generates an output clock signal. The detection unit performs a detection operation to detect the number of delayed clock cycles from the input clock signal to the output clock signal. The control unit changes the delay amount during a delay operation and controls the delay line unit so that the input clock signal is synchronized with the output clock signal. Before the delay operation, the detection unit performs the detection operation multiple times and detects a plurality of numbers of delayed clock cycles. The control unit sets the delay amount for the detection operation and sets the delay amount for the delay operation according to plurality of detected numbers of delayed clock cycles.
