  • Communication device having a two-mode controlled isolation circuit for power transport and bidirectional communication
    Patent number: 7120245
    Abstract: A communication device (1) is described, comprising a powered transceiver (2), a line transceiver (3), an isolation circuit (4) comprising three capacitors Cb1, Cb2 and Cb3, which are coupled between the powered transceiver (2) and the line transceiver (3), and a control circuit (5) arranged for controlling the transport of power from the powered transceiver (2) to the line transceiver (3) and for accomplishing a bi-directional communication across the isolation circuit (4). The control circuit is a two-mode controlled circuit (5), arranged such that during a first mode said power is transported and a communication in one direction is performed, and that during the second mode the communication in the other direction is accomplished.
