2.5V, 3.3V LVPECL FANOUT BUFFER
LVPECL INPUT WITH BUILT-IN 50Ω TERMINATION INTERFACE (3.3V)
The IN /nIN with built-in 50Ω terminations accepts LVDS, by the most common driver types. The input interfaces sug-
LVPECL, LVHSTL, CML, SSTL and other differential signals. gested here are examples only. If the driver is from another ven-
Both VSWING and VOH must meet the VPP and VCMR input require-
ments. Figures 2A to 2E show interface examples for the
HiPerClockS IN/nIN input with built-in 50Ω terminations driven
dor, use their termination recommendation. Please consult with
the vendor of the driver component to confirm the driver termi-
nation requirements.
