Abstract
A printed circuit board includes a high-speed differential signal control chip, first to fourth coupling capacitor pads, first and second connector pads, first and second inductor pads, a number of transmission lines, a power pin, two sharing pads, and two selection pads. Two coupling capacitors can selectively connect the first and second coupling capacitor pads and the two sharing pads or between the third and fourth coupling capacitor pads and the two sharing pads, respectively. Two inductors can connect the first and second inductor pads and the two selection pads respectively, and the first and second inductor pads and the two selection pads can be void.
