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

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
HiPerClockS LVHSTL drivers. If you are using an LVHSTL driver
from another vendor, use their termination recommendation.
