ABSTRACT:
An exemplary PCB includes a first reference layer, a first signal layer, a second signal layer, and a third signal layer in that order, a first differential pair is arranged in the first signal layer in edge-coupled structure and references the first reference layer, a distance between the first signal layer and the second signal layer is greater than a distance between the first reference layer and the first signal layer, a second differential pair is arranged in the second signal layer and the third signal layer in broad-coupled structure. The PCB has a high density layout of transmission lines.
