Abstract
A delay-locked loop circuit includes a phase detector and a coarse-lock detector. The phase detector receives a feedback clock and a first clock to generate first and second phase detecting signals, respectively. The coarse-lock detector generates a coarse-lock signal based on changes of phase of the first and second phase detecting signals.
