A communication device includes a current information storage unitthat stores the bit boundary signal at each of timings at which a sampling clock is updated, a past information storage unitthat takes in and stores a signal stored in the current information storage unitwhen a variation point of a reception signal is detected, and does not update a signal stored therein when no variation point of the reception signal is detected, and a clock selection unitthat selects CLKSELused for the sampling of the reception signal from N-phase clocks based on a signal stored in the current information storage unitwhen a variation point of the reception signal is detected, and selects CLKSELbased on a signal stored in the past information storage unitwhen no variation point of the reception signal is detected.
