3.2 Power and Ground Planes
Power and ground planes need isolation gaps to minimize digital switching noise
effects on the analog signals and components. These gaps need to be at least
1/8-inch wide. They are placed so that digital currents cannot flow through a
peninsula that contains the analog components, signals, and video connector.
Figure 3-1
illustrates a sample layout.
