Abstract
Embodiments of the invention include an integrated circuit including a line driver. The integrated circuit includes a voltage mode driver comprising complementary first and second input voltage drivers, a programmable resistor network and a current mode driver. The programmable resistor network allows the amplitude of the line driver outputs to be controlled based on the particular resistor connections in the programmable resistor network. Also, the differential impedance of the integrated circuit and the common mode impedance of the integrated circuit are based on the resistance values of the resistors in the programmable resistor network.
