Abstract

A signal trace on a printed circuit board (PCB) includes a first trace segment on a first layer of the PCB, the first trace segment having a first end coupled to a transmitter, having a second end, and having a first characteristic impedance that is matched to the transmitter. The signal trace further includes a signal via passing from the first layer of the PCB to a second layer of the PCB, the signal via having a first contact connected to the second end of the first trace segment, having a second contact on the second layer, and having a second characteristic impedance different from the first characteristic impedance. The second characteristic impedance is determined based upon a first distance between the transmitter and the first via.
