DS92LV040A: DS92LV040A can use for LVPECL receiver without external interface circuit?

Hi Jade,

Yes and no.  It's not really a level-shifting / interface circuit, just requirements for using LVPECL.

LVPECL drivers will need some sort of current path to GND.  And a 100 ohm termination will likely be needed at the LV040A input.
