Abstract

See full text

A printed circuit board of an information handling system includes a dielectric layer, adjacent differential pairs, a ground layer, and a ground wall. The adjacent differential pairs are plated on the dielectric layer, and generate crosstalk between each other. The ground wall is in physical communication with and electrically coupled to the ground layer. The ground wall extends substantially perpendicular from the ground layer through the dielectric layer. A top surface of the ground wall is a specific height above a top surface of the adjacent different pairs. The ground wall suppresses the generated crosstalk based on the specific height and a width of the ground wall.
