Abstract
A system board is provided that includes a connector. The connector includes a pinfield. The pinfield includes a set of differential signal conductors to correspond to pins of a set of differential signaling pairs; a set of one or more auxiliary signal conductors to carry auxiliary signals; and a plurality of thru-hole ground vias adjacent to a particular one of the auxiliary signal conductors in the set of auxiliary signal conductors. A method for improving signal integrity in a computer interconnect can include carrying differential signals on a set of differential signal vias in a connector pinfield; carrying sideband signals on a set of sideband vias in the connector pinfield; and reducing via-to-via crosstalk between a particular one of the sideband vias and one of the differential signal vias through one or more thru-hole ground vias adjacent to the particular sideband via in the pinfield.
