NFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS843002I 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
. The 10
Ω
resis-
tor can also be replaced by a ferrite bead.

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 reference clock,
it can be left floating. Though not required, but for additional

All control pins have internal pull-ups or 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.
