1. A driver circuit for receiving input data and generating an output signal to a termination element, wherein when the driver circuit operates as a first mode, the input data has a first bit and second bit, one of the first bit and the second bit is a most significant bit (MSB), and the other one of the first bit and the second bit is a least significant bit (LSB) and the driver circuit comprises:
a pair of differential output terminals, arranged for outputting the output signal, wherein the pair of differential output terminals has a first output terminal and a second output terminal; a first current mode drive unit, coupled to the pair of differential output terminals, for outputting a current from one of the first output terminal and the second output terminal, and receiving the current from the other of the first output terminal and the second output terminal according to the first bit; and a voltage mode drive unit, coupled to the pair of differential output terminals, for providing voltages to the first output terminal and the second output terminal according to at least the second bit. |
