A timing signal generating unit generates timing signals indicating different timings in synchronization with a timing at which a status of a reception signal transitions. A first data signal generating unit generates a first data signal from statuses of the reception signal before and after a timing at which a predetermined first timing signal becomes a specific value, and outputs the first data signal in synchronization with a second timing signal different from the first timing signal. A second data signal generating unit generates a second data signal from statuses of the reception signal before and after a timing at which the second timing signal becomes the specific value, and outputs the second data signal in synchronization with a timing signal different from the first timing signal.
