A printed circuit board (PCB) includes a top outer layer, a bottom outer layer, a signal transmission layer, an inner signal transmission layer, and a via system defined in the PCB. The via system includes two pairs of vias configured to transmit signals from a transmitter to a receiver. A signal transmission pathway is defined in the top outer layer, the signal transmission layer, and the inner signal transmission layer. Signals are sent from the transmitter to a first pair of vias, the signals are transmitted from the first pair of vias to a second pair of vias, and the signals are sent from the second pair of vias to the receiver. The two pairs of vias and the signal transmission pathway provide impedance matching to the signals.
