Please note there have been some changes to SSTL-2 in recent months.
There is a full editorial revision in the works right now to incorporate
the passed changes to it; until the revision is published you can get
the individual changes from the "Council Ballots" page.
Perhaps of particular interest are the changes made under the JC-42.3
DDR DRAM spec. These define fractional-drive SSTL-2 variants for use
in unterminated point-to-point links (such as graphics subsystems or
XGMII).
