  • Systems and methods to reduce differential-to-differential far end crosstalk
    Patent number: 11843383
    Abstract: Example implementations described herein are directed to reducing far end cross talk (FEXT), including differential-to-differential far end crosstalk (DDFEXT) or single ended FEXT through generating and applying a delay shifter/inverter that is cascaded onto a target electrical system and shifts the even-mode and odd-mode propagation delay of a target electrical system to be substantially equal, which in turn reduces FEXT in the overall system.
    Type: Grant
    Filed: June 25, 2021
    Date of Patent: December 12, 2023
    Assignee: Hirose Electric Co., Ltd.

  • Systems and methods to reduce differential-to-differential far end crosstalk
    Patent number: 11581883
    Abstract: A method of manufacturing an electrical system for reducing differential-to-differential far end crosstalk (DDFEXT) includes converting a first S parameter representative of a design of a first electrical system into a differential-only S parameter, generating a second differential-only S parameter configured to add even-mode propagation delay and odd-mode propagation delay of the differential-only S parameter of the electrical system such that a total even-mode propagation delay and odd-mode propagation delay of the differential-only S parameter are substantially equivalent, and reconfiguring a second electrical system from the differential-only S parameter and the second differential-only S parameter.
