Abstract:
1. An integrated circuit including a line driver circuit, comprising: a first input voltage driver having an output; a second input voltage driver having an output and coupled to and complementary with the first input voltage driver; a programmable resistor network coupled between the output of the first input voltage driver, the output of the second input voltage driver, a first output, and a second output; and a current mode arrangement coupled between the first input voltage driver, the second input voltage driver, and the programmable resistor network, wherein the differential impedance of the integrated circuit is based on the resistance of the programmable resistor network, wherein the common mode impedance of the integrated circuit is based on the resistance of the programmable resistor network, and wherein the programmable resistor network controls the output amplitude of the integrated circuit at the first output and at the second output.
