Abstract

An AUX channel amplifier for amplifying data in the AUX channel of a Display Port device. In some embodiments, the amplifier includes a first amplifier coupled to amplify a signal from a source to a sink and a second amplifier coupled to amplify a signal from the sink to the source. A slicer can be utilized to digitize the signal from the source. In some embodiments, a clock and data recovery can be utilized to receive signals from the source and a second clock and data recovery can be utilized to receive signals from the sink. A controller determine the direction of data flow and enables the first amplifier or the second amplifier accordingly.
