  • Bidirectional transreceiver for high speed data system
    Patent number: 5579336
    Abstract: A transceiver circuit for use in a high speed data transmission network is disclosed that provides for simultaneous bidirectional transmission of data over coaxial or twisted pair media for replacing fiber optic cables. A transmitter circuit provides and output data signal to a bridge network. The bridge network develops a cancelling signal and a combined signal. A receiver section includes a high speed subtracting circuit that determines the difference between the cancelling signal and the combined signal to effectively cancel data supplied by the transmitter section.
    Type: Grant
    Filed: October 2, 1995
    Date of Patent: November 26, 1996
    Assignee: Digital Equipment Corporation
