A timing adjustment circuit includes a voltage-controlled delay line, a phase detector, a control voltage generation circuit, and a startup circuit. The voltage-controlled delay line receives an input clock signal and generates multi-phase clocks, a delay amount of each of the multi-phase clocks is changed according to a control voltage. The phase detector detects a phase difference between a first clock and a second clock, the first clock is a reference, the second clock is generated from the voltage-controlled delay line. The control voltage generation circuit generates the control voltage on the basis of the detected phase difference. The startup circuit operates for a certain period after activation, and continuously changes the control voltage between a first voltage and a second voltage.
