  • Publication number: 20230046581
    Abstract: An apparatus and method for reducing differential cross-talk in a pin arrangement of a socket are described. Socket pins within a differential pair use a modified shape to tighten the intra-pair pin coupling to reduce the crosstalk without changing the pin map. The middle vertical segment of one pin of a diagonally adjacent differential pin pair is modified to be closer to the other pin than other corresponding locations of the pins. The spring beam that extends from the middle vertical segment of the one pin is modified to accommodate the package landing pad that the spring beam contacts to maintain a uniform pitch.
