Simple interface LVTTL -> LVPECL How to ?

  1. A simple LVTTL to LVPECL interface without interface IC ? Any info ?

  1. If I want a single ended output from a LVPECL,can I leave the other differential output open (unconnected) ?

Resistive level shifter, 4 resistors maybe. 2 resistors if you have an intermediate supply rail available. I could draw it and post to abse if you want.

Yes. Vcc current will be better balanced if the loads are balanced, but that will almost never matter.
