NFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843004-02 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
resistor along with a 10μF and a .01
μ
F bypass
capacitor should be connected to each V
CCA
.

For applications not requiring the use of the crystal oscillator
input, both XTAL_IN and XTAL_OUT can be left floating. Though
not required, but for additional protection, a 1k
resistor can be
tied from XTAL_IN to ground.

For applications not requiring the use of the test clock, it can be

:
All select pins have internal pull-ups and pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k

All unused LVPECL outputs can be left floating. We recommend
that there is no trace attached. Both sides of the differential output
pair should either be left floating or terminated.
