Abstract
A wired transceiver includes an output stage circuit and an input stage circuit. The output stage operates in one of a first mode and a second mode according to a mode control signal, and transmits multiple output signals to multiple output pads and receives a first set of bias voltages to provide a first overvoltage protection in the first mode, and stops transmitting the output signals and receives a second set of bias voltages to provide the overvoltage protection in the second mode. The input stage circuit receives multiple input signals from the output pads when the output stage circuit operates in the second mode, and attenuates the input signal to provide a second overvoltage protection.
