The present technique relates to a clock generation circuit including a phase difference comparison circuit configured to compare a phase of each of an input clock signal and a feedback signal, and provides a phase difference signal indicating a phase difference between the input clock signal and the feedback signal, a filter circuit configured to suppress a high frequency component in the phase difference signal, an output circuit configured to modulate the phase difference signal in such a manner as to decrease a noise component of a low frequency band and increase a noise component of a high frequency band, and generate and output an output clock signal from the modulated phase difference signal and a reference clock signal, and a frequency dividing circuit configured to divide a frequency of the output clock signal, at a predetermined frequency dividing ratio, and feed it back to the phase comparison circuit.
