Patent ID: 8897178

Claim:
An active transceiver circuit for an electrical communication system using wires or coaxial cables for full-duplex transmission of a low bitrate data signal over and reception of a high bitrate data signal from a single ended transmission medium, the low bitrate data signal having a bitrate at least 3 times lower than the high bitrate data signal and the high bitrate data signal having a maximum slew rate, the active transceiver circuit comprising: an input port configured to receive a low bitrate input data signal, an output port configured to deliver a high bitrate output data signal, a differential input/output port configured to launch a low bitrate data signal into the single ended transmission medium and to receive a high bitrate data signal from the single ended transmission medium, a first and second single ended output driver configured to generate single ended signals to be sent over wires or transmission lines and configured to each shape the low bitrate input data signal to a maximum slew rate that is at least 5 times smaller than said maximum slew rate of the high bitrate data signal, and to deliver, on their respective output nodes, the shaped low bitrate input data signal, and a high bitrate receiver configured to receive the signals at output nodes of the first and second single ended output drivers, and to generate a high bitrate output data signal on the output port.
