1. A bidirectional repeater for repeating an electrical signal traversing a conductive line coupled between a gateway node and a sensor, the bidirectional repeater comprising:

  • a first input-output port coupled to the gateway node;

    a second input-output port coupled to the sensor;

    a first transceiver configured to receive a synchronization signal from the first input- output port and to transmit a resynchronized data signal to the first input-output port;

    a second transceiver configured to transmit the synchronization signal to the second input-output port and to receive a data signal from the second input-output port; and

    a repeater circuit coupled to the first and second transceivers and configured to pass through the synchronization signal without re-clocking the synchronization signal, and to resynchronize the data signal to generate the resynchronized data signal.
