Printed circuit board, printed wiring board, and differential transmission circuit
Abstract:
Provided is a printed circuit board including a first semiconductor device and a second semiconductor device mounted on a printed wiring board, the printed wiring board including a first and a second differential signal wirings each formed of a pair of signal transmission lines. The pair of signal transmission lines forming the first differential signal wiring are wired to have a relative arrangement in which one signal transmission line and another signal transmission line cross with each other at least once in the first differential signal wiring in a wiring direction thereof. The pair of signal transmission lines forming the second differential signal wiring are wired to have a relative arrangement in which one signal transmission line and another signal transmission line cross with each other at least once in the second differential signal wiring in a wiring direction thereof.
