Abstract
The invention provides a delay line circuit. The delay line circuit includes a delay line section and a feedback selection section. The delay line section receives an input clock signal and a feedback clock signal and delays one of the input clock signal and the feedback clock signal to generate an output clock signal, wherein the delay line section includes a plurality of delay units coupled in series. The feedback selection section is coupled to the delay line section and feedbacks the output clock signal to one of the delay units to serve as the feedback clock signal based on a selection signal. Wherein, one of the input clock signal and the feedback clock signal is delayed by a specific number of the delay units based on the selection signal to changes the frequency of the output clock signal.
