Abstract
A transmitter circuit including: a current driver which current-drives differential signal lines; and a voltage driver which is electrically disconnected from at least one of the differential signal lines in a normal transfer mode, and is electrically connected to the at least one of the differential signal lines and voltage-drives the at least one of the differential signal lines in a power-down mode. The voltage driver outputs a power-down voltage for setting a receiver circuit to the power-down mode or a wakeup voltage for canceling the power-down mode of the receiver circuit, to the at least one of the differential signal lines. The current driver transmits a power-down command to the receiver circuit by current-driving the differential signal lines in the normal transfer mode.
