Asymmetric full duplex communication including device power communication
摘要:
An active transceiver circuit (212) for transmission of a low bitrate data signal (177) over and reception of a high bitrate data signal (166R) from a single ended transmission medium (105), the transmission medium (105) comprising an inner conductor (107) and a conductive shield layer (109), comprises:
an input port (204) for receiving a low bitrate input data signal (101),
an output port (202) for delivering a high bitrate output data signal (102),
a differential input/output port (203) for launching a low bitrate data signal (177) into the single ended transmission medium (105) and for receiving a high bitrate data signal (166R) from the single ended transmission medium (105),
a first and second single ended output driver (191, 192) adapted for each delivering, on their respective output nodes (111, 112), the low bitrate input data signal (101) shaped to a maximum slew rate that is at least 5 times smaller than the maximum slew rate of the received high bitrate data signal (166R), and
a high bitrate receiver (117) for receiving the signals at output nodes (111, 112) of the first and second single ended output drivers (191, 192), and for generating a high bitrate output data signal (102) on the output port (202).
The transceiver circuit (212) may be incorporated in a transceiver (200).
