The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, HCSL and
other differential signals. Both differential signals must meet
the V
interface 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
