摘要： A differential signal output device is disclosed that outputs transmission data as a differential signal. The device includes a first differential signal generation circuit that amplifies a signal representing the transmission data and generates the differential signal from the amplified signal; a dummy data generation circuit that is synchronized with a reference clock of the transmission data and generates dummy data that change only in a bit where the transmission data do not change; and a second differential signal generation circuit that amplifies a signal representing the dummy data and generates another differential signal from the amplified signal.

摘要： A multiphase delay unit causes a different delay time to a reference clock to generate a multiphase clock having a different phase. A multiphase sampling unit samples the input signal using the multiphase clock, and outputs multiphase sampling data. A phase selecting unit detects a phase relation of the multiphase clock using the multiphase sampling data, and selects output data from the multiphase sampling data based on data obtained by detecting the phase relation of the multiphase clock.

摘要： An amplifier circuit performs an amplification of a carrier signal received by a transmitting and receiving unit. The amplifier circuit includes an impedance matching circuit that performs matching of an impedance of the amplifier circuit when the transmitting and receiving unit and the amplifier circuit are connected. A superposition wave generating unit generates a superposition wave which is superimposed on the received carrier signal. A driver outputs an amplified carrier signal which is obtained by adding the superposition wave to the received carrier signal. An amplitude detecting unit detects whether the received carrier signal is a predetermined carrier signal superimposed with a predetermined communication signal, based on changes of an amplitude value of the received carrier signal. When the predetermined carrier signal is detected, the amplifier circuit outputs the amplified carrier signal.
