LVPECL FREQUENCY SYNTHESIZER
The schematic of the ICS8430I-61 layout example used in
this layout guideline is shown in Figure 7A. The ICS8430I-61
recommended PCB board layout for this example is shown
in Figure 7B. 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.
