CRYSTAL INPUT INTERFACE
The ICS843001-21 has been characterized with 18pF paral-
lel resonant crystals. The capacitor values shown in Figure 2
Figure 2. CRYSTAL INPUt INTERFACE
below were determined using a 19.44MHz, 18pF parallel reso-
nant crystal and were chosen to minimize the ppm error.

APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843001-21 provides
separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
CC, VCCA, and VCCO_x
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 1 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.
