Abstract:
A multimode line driver circuit is provided. The multimode line driver circuit has a first driver circuit for receiving a first differential input signal and transmitting a first differential output signal, and a second driver circuit for receiving a second driver circuit for receiving a second differential input signal and transmitting a second differential output signal. The multimode line driver circuit also has a first switch coupling the first driver circuit to a first power supply and a second switch coupling the second driver circuit to a second power supply. The multimode line driver circuit also has a transformer coupled to the output interface for transforming the first differential output and the second differential output and a mode controller configured to close the first switch in the first mode and to close the second switch in the second mode.
