sysI/O Differential Electrical Characteristics
LVDS
Differential HSTL and SSTL
Differential HSTL and SSTL outputs are implemented as a pair of complementary single-ended outputs. All allow-
able single-ended output classes (class I and class II) are supported in this mode.
For further information about LVPECL, RSDS, MLVDS, BLVDS and other differential interfaces please see the list
of additional technical information at the end of this data sheet.
