Differential Clock Input Interface
The CLK/nCLK accepts HCSL, LVDS, LVPECL and SSTL and other
differential signals. Both differential signals must meet the V
V
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.
