The ICS843051 has been characterized with 18pF parallel
resonant crystals. The capacitor values, C1 and C2, shown in
Figure 2 below were determined using a 26.04167MHz, 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 ICS843051 provides sepa-
rate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
CC
, and V
CCA
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
resistor along with a 10
μ
F and a .01
μ
F bypass
capacitor should be connected to each V
CCA
pin.
