LVPECL and floating inputs



Software guy here working on a simple project thats becoming complicated

Please imagine the following scenario:
device with lvpecl inputs. Possibility that the inputs may float (left
unconnected). I reckon I should force the inputs to a default level,

If this were a TTL device, I would tie the input to vcc via a pullup
or pull down. But its a differential - so I guess I need a voltage divider to balance the two inputs such that theres a difference of say
100mv between the two

How will this affect things when an input IS connected?

I know what you are thinking - is this dude dense or what?
I am going to go down to the basement and fish out my ac/dc analysis
book and read up on thevenin,superposition,mesh networks and various
ways of analyzing circuits.

Its been awhile

Any pointers would help
.
