ICS84330

The schematic of the ICS84330 layout example used in

this layout guideline is shown in

Figure 6A. The ICS84330

recommended PCB board layout for this example is shown

in

Figure 6B. This layout example is used as a general guide-

line. 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.
