A high-speed serial ATA physical layer transmits data over a communications medium using a serial ATA protocol. A serial ATA control circuit controls operation of the serial ATA physical layer. A serial ATA multiplexer outputs a serial ATA signal and has a plurality of input lines for receiving input data and a control input that communicates with the serial ATA control circuit. A serial ATA analog front end includes a first differential driver that communicates with the serial ATA multiplexer and provides a first gain to the serial ATA signal and a serial ATA pre-emphasis circuit that provides pre-emphasis to the serial ATA signal to alter a transmission characteristic of the serial ATA signal.
