摘要： A printed circuit board (PCB) may include a plurality of horizontally disposed signal layers. The PCB may include a first vertically disposed differential via electrically connected to a first horizontally disposed signal layer, of the plurality of horizontally disposed signal layers, and a second horizontally disposed signal layer of the plurality of horizontally disposed signal layers. The PCB may include a second vertically disposed differential via electrically connected to the first signal horizontally disposed layer and the second horizontally disposed signal layer. The PCB may include a first set of clearances encompassing the first vertically disposed differential via and the second vertically disposed differential via, a second set of clearances encompassing the first vertically disposed stub, and a third set of clearances encompassing the second vertically disposed stub.
