Patent ID: 8080738

Claim:
A printed circuit comprising: a substrate having a pair of opposite sides; a pair of signal vias extending through at least one of the sides and at least partially through the substrate between the sides, the signal vias being arranged in a differential signal pair; aggressor vias extending through at least one of the sides and at least partially through the substrate between the sides, the aggressor vias being arranged in differential aggressor pairs that are arranged in a pattern around the differential signal pair, wherein linear paths are defined between each of the signal vias of the differential signal pair and the aggressor vias of each differential aggressor pair, each linear path extending from a center of the corresponding signal via of the differential signal pair to a center of the corresponding aggressor via, at least some of the differential aggressor pairs being arranged along the substrate directly adjacent the differential signal pair; and ground vias extending through at least one of the sides and at least partially through the substrate between the sides, the ground vias being arranged around the differential signal pair, at least one ground via being positioned along each linear path between the signal vias of the differential signal pair and the aggressor vias of each of the differential aggressor pairs that is directly adjacent the differential signal pair.
