Subject: [IBIS-Users] pullup/pulldown range LVDS

Dear IBIS users,
For ECL the pullup/pulldown curves only have to cover the 0-2.2V range
(relative to Vcc). This is because of the limited voltage swing, which is
centered around a DC voltage far away from the supply rails.
How about LVDS? It has a similar output swing. Is it needed to cover the
"regular" voltage range of -3.3-6.6V (for 3.3V supply)? It's rather a
waste of accuracy for the typical operation area (less points remain).
With kind regards,
Ir. Erik van der Ven
