[SI-LIST] Re: diff pair signal

Gil, with LVDS I think that would be a very bad idea.  LVDS is low swing 
and the swing references the internal power / ground nodes.  If someone 
were going to try and cheat to reduce interconnects, I would take a single 
LVDS pair and hold it at a static level.  Then use a 1:1 resistor divider 
between the two output leads as the reference for the single-ended "LVDS" 
signals.

Regards,


Steve.
