A transmitting apparatus includes a first circuit to which a base clock and a first clock condition are input, the first circuit outputting a first enable signal based on the base clock and the first clock condition; a second circuit to which the base clock and a second clock condition are input, the second circuit outputting a second enable signal based on the base clock and the second clock condition; a first frame processing circuit receiving a first frame input signal and the first enable signal to output a first frame output signal in synchronization with the first enable signal; and a second frame processing circuit receiving a second frame input signal and the second enable signal to output a second frame output signal in synchronization with the second enable signal.
