Abstract:
An enhanced cross-talk reducing connector footprint on a PWB, with the PWB including a ground layer, the enhance connector footprint for coupling a connector having ground pins arranged in columns between signal pins, said enhanced cross-talk reducing connector footprint comprising:a standard connector footprint having signal and ground vias geometrically arranged to be congruent to the connector footprint to receive corresponding signal and ground pins of the connector, with signal vias disposed along at least a first edge of the standard connector footprint, and with the ground vias in the standard footprint for coupling connector ground pins to the ground layer of the PWB; and a first row of extra ground vias disposed outside the connector footprint and substantially parallel to the first edge of the connector footprint to provide shielding and reduce cross-talk between signal pins disposed along the first edge, where ground pins are not mated to the extra ground vias and where the extra ground vias are coupled to ground vias in the standard connector footprint and to the ground pins of the connector through the ground layer of the PWB.
