  • Cable detect and EMI reduction apparatus and method
    Patent number: 6462435
    Abstract: A repeater, useable for connecting switches in a data communication network, is provided in a distributed and/or modular fashion. The repeater includes a plurality of separate and distinct components or modules connected to or at least partially housed in, the various switches which the repeater modules couple. Preferably, the repeater autodetects and/or autoconfigures some or all aspects of repeater operations, such as detecting and/or configuring in response to appropriate or approved cable-type connections. A conductive, sealing member on a cable connector substantially reduces or eliminates EMI.
    Type: Grant
    Filed: June 11, 1999
    Date of Patent: October 8, 2002
    Assignee: Cisco Technology, Inc.

  • Method and apparatus for a low voltage high current bi-directional termination voltage regulator
    Patent number: 5945814
    Abstract: A low voltage high current bi-directional termination voltage regulator for use in a bus termination circuit in a repeater stack is disclosed that includes an operational amplifier, a bipolar transistor current source circuit, and a bipolar transistor current sink circuit. The operational amplifier is configured to source current to a first node when the output voltage at a second node is pulled below a nominal termination voltage and configured to sink current from the first node when the output voltage at the second node is pulled above the nominal termination voltage, the second node being connected to a termination load. The bipolar transistor current source circuit is configured to source current to the second node when the operational amplifier sources current to the first node so that the output voltage at the second node is pulled up as a result of the current sourced by the bipolar transistor current source circuit through the second node to the termination load.
