  • Line driver and method of operating the same
    Patent number: 7339997
    Abstract: A line driver coupled to a transmission path having line characteristics associated therewith and a method of operating the same. In one embodiment, the line driver includes a driver stage configured to send a signal along the transmission path. The line driver also includes a switching network, coupled to the driver stage, configured to adaptively select a power level to send the signal as a function of the line characteristics of the transmission path.
    Type: Grant

  • System for efficiently powering repeaters in small diameter cables
    Patent number: 5412716
    Abstract: A system of impedance matching is provided to match the total impedance of the cable system to the total impedance of the powered elements such as the repeaters. The source impedance of the power supplies may be considered as part of the cable impedance. By matching impedances, the source voltage for driving the electronics is advantageously minimized.
