I have a 68-pin ribbon cable terminated with an AMP 869794-1 "Differential
Terminator"; some documents describe certain multimode LVD/SE terminators as
capable of sensing HVD and either properly terminating it or tri-stating off
the bus. There is nothing on the part which states what modes it supports.

Does anyone know the capabilities of this part?

Thanks,

Michael

It's simply a passive differential terminator. There's nothing but resistors
on the signal lines, so it's clearly not a multi-mode terminator...

Thanks for the link. I can't imagine where I found 68pin internal HVD
cables with terminators as none of my machines have an HVD HBA (AFAIK)
but the diagram doesn't lie ;)
