1. A printed circuit board of an information handling system, the printed circuit board comprising:
a differential pair including first and second traces;
first and second ground traces routed between the first and second traces of the differential pair; and
a ground via located between the first and second ground traces,
wherein the first ground trace includes a first length on a first side of the ground via and the second ground trace includes a second length on a second side of the ground via, wherein the first length is longer than the second length,
wherein the first and second ground traces and the ground via combine to create a common mode signal filter, the common mode signal filter to reset a skew of the differential pair.
