ADVANCE INFORMATION
APPLICATION INFORMATION
CRYSTAL INPUT INTERFACE
The ICS843101-312 has been characterized with 18pF
parallel resonant crystals. The capacitor values shown in
Figure 3 below were determined using a 25MHz, 18pF par-

allel resonant crystal and were chosen to minimize the
ppm error.
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843101-312 pro-
vides separate power supplies to isolate any high switch-
ing noise from the outputs to the internal PLL. V
CC, VCCA, and
V
CCO 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. Figure 2 illustrates how
a 10
Ω resistor along with a 10F and a .01μF bypass
capacitor should be connected to each V
CCA. The 10Ω resis-
tor can also be replaced by a ferrite bead.
