The ICS843034-01 has been characterized with 18pF paral-
lel resonant crystals. The capacitor values, C1 and C2, shown
in
Figure 4
below were determined using a 25MHz, 18pF
parallel resonant crystal and were chosen to minimize the
ppm error. The optimum C1 and C2 values can be slightly
adjusted for different board layouts.

The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals. Both V
and V
must meet the
V
and V
input requirements. Figures 5A to 5D show inter-
face examples for the HiPerClockS CLK/nCLK input driven by
the most common driver types. The input interfaces suggested

here are examples only. Please consult with the vendor of the
driver component to confirm the driver termination requirements.
For example in
Figure 5A,
the input termination applies for ICS
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver
from another vendor, use their termination recommendation.
