Abstract
A multi-layer printed circuit board that includes a first layer and a second layer that have first and second signal traces, respectively. The multi-layer printed circuit board includes a via that couples a signal transmitting component to the second signal trace and a throttling member, which is coupled to the first signal trace. The throttling member reduces the speed at which a first signal routed over the first signal trace travels when compared to the speed at which that signal would have traveled had the throttling member been absent.
