APPLICATION INFORMATION
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. To achieve optimum jitter per-
formance, power supply isolation is required. The ICS841654I
provides separate power supplies to isolate any high switching
noise from the outputs to the internal PLL. V
DD, VDDA, VDDOA and
V
DDOB should be individually connected to the power supply
plane through vias, and 0.01F bypass capacitors should be
used for each pin.
Figure 1 illustrates this for a generic V
DD pin
and also shows that V
DDA requires
that an additional10
Ω
resistor along with a 10F bypass capacitor be connected to
the V
DDA pin.

INPUTS:
CRYSTAL INPUTS
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.
REF_IN INPUT
For applications not requiring the use of the reference clock,
it can be left floating. Though not required, but for additional
protection, a 1k
Ω resistor can be tied from the REF_IN to ground.
LVCMOS CONTROL PINS
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k
Ω resistor can be used.
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
OUTPUTS:
HCSL OUTPUTS
All unused HCSL 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.
LVCMOS OUTPUT
The unused LVCMOS output can be left floating. We recommend
that there is no trace attached.
