Abstract:
1. A semiconductor circuit, comprising: a first terminal for inputting a first differential signal when an input method is a differential input method, and for inputting a first signal for output when the input method is a single input method; a second terminal for inputting a second differential signal different from the first differential signal when the input method is the differential input method, and for inputting a second signal for output when the input method is the single input method; a single input circuit for retrieving the first signal for output at a timing according to a clock signal when the input method is the single input method according to a method signal indicating whether the input method is the differential input method or the single input method, and for outputting the first signal for output as a first output signal, said single input circuit being arranged to retrieve the second signal for output at the timing according to the clock signal, and to output the second signal for output as a second output signal; a differential amplifier for outputting a differential voltage signal according to a difference between the first differential signal and the second differential signal when the input method is the differential input method; and a differential input circuit for retrieving the differential voltage signal at a first timing according to the clock signal, and for outputting the differential voltage signal as a first output signal, said differential input circuit being arranged to retrieve the differential voltage signal at a second timing different from the first timing according to the clock signal, and to output the differential voltage signal as a second output signal.
