NFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843001I-22 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 1 illustrates how
a 10
Ω
resistor along with a 10μF and a .01
μ
F bypass
capacitor should be connected to each V
