ABSTRACT:
A transceiver provides a high-speed transmission signal using shared resources and reduced area. A differential amplifier has its current source/sink connected to a supply terminal. A multiplexing circuit is configured to connect an input of the differential amplifier to an I/O pad so as to output a received input/output signal to internal integrated circuit logic during one mode, or alternatively connect an output of the differential amplifier to the I/O pad so as to output a signal received from the internal integrated circuit logic for input/output during another mode. A level translation operation on the signal may be performed with respect to outputting the signal received from the internal integrated circuit logic.
