Patent ID: 7012447

Claim:
A signal transmitting/receiving apparatus, comprising: a transmitting device for transmitting a first data and a second data; a receiving device for receiving the first data and the second data; a data line for transmitting the first data and the second data; wherein the transmitting device and the receiving device are connected to each other through the data line, the transmitting device comprising: a driver circuit for outputting the first data to the data line; and a circuit for outputting the second data to the data line, the receiving device comprising: a terminating resistor connected to the data line; a receiver circuit for detecting the first data from the data line; and a bias generating means for generating a bias voltage applied to the terminating resistor, the bias generating means setting the bias voltage based on the second data from the data line, wherein; the data line comprises a pair of differential lines; and the terminating resistor short circuits between the pair of differential lines.
