Abstract
A divider has a clock generation circuit which combines a first trigger clock and a second trigger clock having a first phase difference, so as to generate a third clock having pulse edges corresponding to pulse edges of the first trigger clock and the second trigger clock; an output dividing circuit which divides the frequency of the third clock in half so as to generate a first differential output clock and a second differential output clock having a duty ratio corresponding to the first phase difference; and a phase correction circuit which detects a phase of the first output clock or the second output clock at a timing of the pulse edge of the first trigger clock or the second trigger clock, so as to generate a phase correction signal for resetting the output dividing circuit when the detected phase is not a normal phase.
