Abstract
A line driver circuit has first and second differential input terminals and first and second differential output terminals, and is configured to interface with first and second termination impedances coupled between the first and second differential output terminals, respectively, and first and second transmit chain output terminals, respectively. The line driver circuit includes an amplifier circuit having first and second input terminals coupled to the first and second differential input terminals of the line driver circuit, respectively, and first and second output terminals coupled to the first and second differential output terminals of the line driver circuit, respectively, and an impedance switching circuit coupled between the first and second output terminals of the amplifier circuit. The impedance switching circuit switches between a first switching mode and a second switching mode, wherein in the first switching mode a first switching configuration is established resulting in a first output impedance.
