Abstract
A transmission circuit includes a filter circuit configured to compensate for degradation of a multiplexed signal, based on a tap coefficient to be updated based on a first signal and a second signal which are time-division-multiplexed to the multiplexed signal, a phase locked loop (PLL) circuit configured to control, based on control information corresponding to phases of the first signal and the second signal, a frequency of a clock signal to be synchronized with the multiplexed signal whose degradation has been compensated, and a control circuit configured to generate, in response to an interruption of an input of the first signal or the second signal, the control information corresponding to the phase of the first signal or the second signal of which the interruption is not detected so as to output the control information to the PLL circuit.
