2.5V LVPECL Input with Built-In 50 Termination Interface
The IN /nIN with built-in 50 terminations accept LVDS, LVPECL,
CML and other differential signals. Both signals must meet the V
IN
and V
IH
input requirements. Figures 3A to 3D show interface
examples for the IN/nIN with built-in 50 termination input driven
by the most common driver types. The input interfaces suggested
here are examples only. If the driver is from another vendor, use
their termination recommendation. Please consult with the vendor
of the driver component to confirm the driver termination
requirements.
