PURPOSE: An output circuit is provided to reduce jitter due to the limit of a swing width of an output signal with a shifted level by reducing the swing width of the output signal with the same level. CONSTITUTION: A signal selector(303) outputs a first input signal and a second input signal in response to a phase signal. An output level controller(301) controls the level of the output signal of a signal selector using the first and second input signals and reduces the swing width of the output signal if the levels of the first and second input signals are the same.
