NFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. The ICS84320I-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
a 24
Ω
resistor along with a 10
μ
F and a .01
μ
F bypass
capacitor should be connected to each V
CCA
pin.

:
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
Ω
resistor can be tied from XTAL_IN to ground.
TEST_CLK I

For applications not requiring the use of the test clock, it can
be left floating. Though not required, but for additional
protection, a 1k
Ω
resistor can be tied from the TEST_CLK to
ground.

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.
