The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals. Both V
and V
must meet the
V
and V
input requirements. Figures 4A to 4D show inter-
face examples for the HiPerClockS CLK/nCLK input driven by
the most common driver types. The input interfaces suggested

here are examples only. Please consult with the vendor of the
driver component to confirm the driver termination requirements.
For example in Figure 4A,the input termination applies for ICS
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver
from another vendor, use their termination recommendation.

NPUT
:
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

All select pins have internal pull-ups and pull-downs;

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.
