Differential Clock Input Interface
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals. Both 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 open emitter LVHSTL
drivers. If you are using an LVHSTL driver from another vendor,
use their termination recommendation.
