Abstract
A computer system includes a multi-layer circuit board having first and second routing layers. A component including pads is mounted on the first layer. Crosstalk protection is provided by a plurality of ground vias and signal vias adjacent to the component and extending between the first and second layers. A first circuit trace extends from a first pad along the first layer and between two adjacent ones of the ground vias. A second circuit trace extends from a second pad along the first layer to a signal via at the first layer and from the signal via along the second layer between the two adjacent ground vias.
