The ICS843004I-04 has been characterized with 18pF
parallel resonant crystals. The capacitor values shown in
Figure 2
below were determined using a 19.44MHz,
18pF parallel resonant crystal and were chosen to mini-
mize the ppm error.

NFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843004I-04 pro-
vides separate power supplies to isolate any high switch-
ing noise from the outputs to the internal PLL. V
, 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.
