The schematic of the ICS84314 layout example used in this layout

guideline is shown in

Figure 6A.The ICS84314 recommended PCB

board layout for this example is shown in

Figure 6B. 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.
