摘要

1. Use differential signaling whenever possible. 2. Control your return currents as well as your "signal" currents. 1.1 Design your return path - 1.2 Stitch reference planes at transitions 3. Use blind and/or buried vias when possible 4. Avoid long stubs and switching reference planes 5. Increase stub Zo for some improvement of long stubs.
