摘要:
A printed circuit board includes a differential signal via pairs to route differential signal between layers of the printed circuit board. A first differential signal via pair is oriented in a first orientation and a second differential signal via pair is oriented perpendicular to the first orientation. The second differential signal via pair is located such that a midpoint of a first line segment drawn between centers of first and second vias of the second differential signal pair intersects a first ray drawn from a center of a first via of the first differential signal via pair through a center of a second via of the first differential signal via pair. Further, the second differential signal via pair is located such that the midpoint of the first line segment is at a characteristic via-to-via pitch distance for the printed circuit board from the center of the second via of the first differential signal via pair.
