Abstract
A delay locked loop includes a delay line, a phase detector, a controller, an output clock generator, and a feedback circuit. The delay line receives an input clock signal and a control code, and generates a delayed clock signal by delaying the input clock signal according to the control code. The phase detector receives a reference clock signal and a feedback clock signal, and detects a phase difference between the reference clock signal and the feedback clock signal to generate phase comparison information. The controller generates the control code and a switching signal according to the phase comparison information. The output clock generator selects the delayed clock signal or an inverted signal of the delayed clock signal according to the switching signal to generate an output clock signal. The feedback circuit generates the feedback clock signal according to the output clock signal.
