The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals. Both differential signals must meet
the 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
2A, the input termination applies for IDT LVHSTL drivers. If you
are using an LVHSTL driver from another vendor, use their
termination recommendation.
