Compensation for length differences in vias associated with differential signaling
Abstract:
A circuit may include a differential via that may include a first via having a first-via length and a second via having a second-via length longer than the first-via length. The circuit may also include a differential stripline coupled to the differential via. The differential stripline may include a first trace and a second trace that are broadside coupled to each other over at least a portion of the differential stripline to form a broadside coupled portion of the differential stripline. The first trace may be coupled to the first via and may have a first-trace length. The second trace may be coupled to the second via and may have a second-trace length. The broadside coupled portion of the differential stripline may be offset from a plane intersecting substantially half-way between the first via and the second via such that the second-trace length is shorter than the first-trace length.
