A signal transceiver apparatus suitable for a wired signal transceiver system includes a differential signal transmitter, an impendence matching control module and a signal receiver. The signal transmitter has an output terminal which is connected to a transceiver wire. The signal transmitter includes a first impendence tuner and is used to receive a control signal so as to tune impendence of the first impendence tuner according to the control signal. Moreover, the impendence matching control module generates the control signal according to a compare signal and a lock signal. Besides, the signal receiver generates the lock signal and the compare signal according to a compare result between a current flowing through the first impendence tuner and a reference current. |
