I would appreciate if you would not use all these acronyms.
"YMMV. HTH. HAND." etc...
I have no idea what they stand for, and I bet many of the foreign
readers on the list have the same problem. I know it takes a lot of
time to write out frequently used common expressions, and in this
world we have everything but time, but if this is such a big problem
for you, come up with some nifty keyboard macros that will automatically
write it out for you on pressing one or a few keys.
Thanks,
Arpad

SSTL is pretty completely specified, but "full-swing" could be
anything. Do you mean rail-to-rail reflected-wave switching on
a point-to-point connection with centered diffamp receivers (sort
of like AGP) or what?
Source-terminated full-swing with precision receivers can be as
fast as SSTL and use less power. Emphasis: _can_
OTOH if you have a multi-drop bus it gets very hard to keep the
reflections from seriously degrading performance. Also, series
terminating an IC driver is iffy; doing it on the silicon gives
a pretty wide range of incident wave amplitudes across process
and temperature. Doing it off-chip is ugly for other reasons.
YMMV. HTH. HAND.
