The ICS843031-01 has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown in
Figure 2 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.

As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843031-01 provides
separate power supplies to isolate any high switching noise
from the outputs to the internal PLL. V
and V
should be
individually connected to the power supply plane through vias,
and bypass capacitors should be used for each pin. To achieve
optimum jitter performance, power supply isolation is required.
