10.2 Avoiding Typical Design/Layout Problems
Avoid ground loops or running digital and analog traces parallel to each other (side-by-side) on the same
PCB layer. When traces must cross over each other, do so at 90 degrees. Running digital and analog
traces at 90 degrees to each other from the top to the bottom side as much as possible will minimize
capacitive noise coupling and crosstalk.
