LAYOUT GUIDELINE
The schematic of the ICS8430B-71 layout example used in this
layout guideline is shown in
Figure 5A. The ICS8430B-71
recommended PCB board layout for this example is shown in
Figure 5B. This layout example is used as a general guideline.
The layout in the actual system will depend on the selected
component types, the density of the components, the density
of the traces, and the stack up of the P.C. board.
