Flexible input/output transceiver

摘要

An I/O transceiver includes a driver with a feedback circuit having a mode select signal input, a serial data signal input, and a driver output signal input. The feedback circuit can provide a feedback control signal that is coupled to a pre-driver circuit. The pre-driver circuit can modify a data signal in response to the feedback control signal and the data signal. A driver circuit is coupled to the pre-driver circuit and can provide a driver output signal responsive to the modified data signal. A receiver can be coupled to the driver to receive the driver output signal. The receiver includes a level shifting circuit that shifts the received signal to a voltage level determined by a selected signaling interface.
