This application note is intended to recommend methods to reduce electromagnetic interference (EMI) by using careful board layout and routing techniques. In advanced systems, where timing is important, good electrical design practices will minimize EMI, cross talk, and overall performance problems. Noise is harmful because it can result in data corruption and false switching in downstream devices. Good design practices are essential in meeting EMI and ESD requirements, and to achieve maximum line performance. These practices minimize high-speed digital switching noise, common-mode noise, and provide shielding between internal circuits and the environment.
