Abstract
A frequency divider circuit is provided. The frequency divider circuit processes multiple input clocks. The frequency divider circuit includes a frequency dividing circuit and a retiming circuit. The frequency dividing circuit generates an intermediate clock according to a first subgroup of the input clocks. The retiming circuit generates multiple output clocks according to a second subgroup of the input clocks and the intermediate clock. The periods of the input clocks are all a first period, and the periods of the output clocks are all a second period. The first period is smaller than the second period. The frequency dividing circuit and the retiming circuit operate according to a mode control signal which determines a ratio of the first period to the second period.
