DIFFERENTIAL CLOCK INPUT INTERFACE
The CLKx /nCLKx accepts LVDS, LVPECL, LVHSTL, SSTL,
HCSL and other differential signals. Both V
SWING and VOH
must meet the V
PP and VCMR input requirements.
Figures 3A
to 3D show interface examples for the HiPerClockS CLKx/
nCLKx input driven by the most common driver types. The
input interfaces suggested here are examples only. Please

ICS HIPERCLOCKS LVHSTL DRIVER
consult with the vendor of the driver component to confirm
the driver termination requirements. For example in Figure
3A, the input termination applies for ICS HiPerClockS LVHSTL
drivers. If you are using an LVHSTL driver from another ven-
dor, use their termination recommendation.

INPUTS:
CLK/nCLK INPUT:
For applications not requiring the use of the differential input,
both CLK and nCLK can be left floating. Though not required,
but for additional protection, a 1k
Ω resistor can be tied from
CLK 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:
LVPECL OUTPUT
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.
