CRYSTAL INPUT INTERFACE
The ICS843011-01 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.
POWER SUPPLY FILTERING TECHNIQUES
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843011-01 provides
separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
CC and VCCA 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 10μF and a .01μF bypass
capacitor should be connected to each V
CCA pin.
