NFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843002I-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.
