According to one embodiment, a printed circuit board (PCB) is disclosed. The PCB includes a first functional unit block (FUB) and differential traces coupled to the first FUB. The first FUB transmits high-speed serial data. The differential traces carry the high-speed serial data from the first FUB. In addition, the differential traces crossover on the same layer of the PCB while maintaining a constant impedance.
