Abstract
A circuit system is disclosed. In one example, the circuit system includes a clock tree circuit with multiple lanes to which a clock signal is distributed. A duty correction circuit is provided for each of the multiple lanes, and corrects a duty ratio of the clock signal. A clock gating circuit group has a clock gating circuit for each of the multiple lanes and receives, as input, the clock signal from the duty correction circuit. The clock gating circuit group starts output of the clock signal from each of a plurality of the clock gating circuits in a predetermined period. A variable delay circuit is provided in association with each of a plurality of the duty correction circuits and is capable of changing a delay time of a control signal that controls a timing of starting output of the clock signal from the clock gating circuit.
