Differential Clock Input Interface
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL and
other differential signals. The differential signal must meet the V
and V
examples for the 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 3A, the input
termination applies for IDT open emitter LVHSTL drivers. If you are
using an LVHSTL driver from another vendor, use their termination
recommendation.
