The ICS843003I-01 has been characterized with 18pF par-
allel resonant crystals. The capacitor values shown in

ECHNIQUES
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843003I-01 provides
separate power supplies to isolate any high switching
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. Figure 2 illustrates how

capacitor should be connected to each V

pin.
