The schematic of the ICS8430-61 layout example used in this
layout guideline is shown in Figure 5A. The ICS8430-61 rec-
ommended 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.

The ICS8430-61 has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown
in Figure 4 below were determined using a 25MHz, 18pF par-
allel resonant crystal and were chosen to minimize the ppm
error. These same capacitor values will tune any 18pF paral-
lel resonant crystal over the frequency range and other pa-
rameters specified in this data sheet. The optimum C1 and C2
values can be slightly adjusted for different board layouts.
