PCB Layout Design Introduction:
In high-speed design, the characteristic impedance of controlled impedance boards and lines is one of the most important and common problems. First understand the definition of a transmission line: A transmission line consists of two conductors of a certain length, one for sending a signal and the other for receiving a signal (remember the concept of "loop" instead of "ground"). In a multilayer board, each trace is part of a transmission line, and the adjacent reference plane can act as a second trace or return. The key to a line being a "good" transmission line is to keep its characteristic impedance constant throughout the line.
