3.3V Differential Input with Built-In 50
The IN /nIN with built-in 50Ω terminations accept LVDS, LVPECL,
LVHSTL, CML, SSTL and other differential signals. Both signals must
meet the V
interface examples for the IN/nIN input with built-in 50Ω terminations
driven by the most common driver types. The input interfaces
