The LVDS Standard
LVDS is currently standardized by the TIA/EIA (Telecommunications Industry
Association/Electronic Industries Association) ANSI/TIA/EIA-644-A (LVDS) Standard.
The generic (multi-application) LVDS standard, ANSI/TIA/EIA-644-A, began in the TIA Data
Transmission Interface committee TR30.2 in 1995. It was revised and published as
ANSI/TIA/EIA-644-A in 2001. The ANSI/TIA/EIA standard defines driver output and
receiver input characteristics, thus it is an electrical-only standard. It does not include
functional specifications, protocols or even complete cable characteristics since these are
application dependent. ANSI/TIA/EIA-644-A is intended to be referenced by other
standards that specify the complete interface (i.e. connectors, protocol). This allows it to be
easily adopted into many applications. To learn more about LVDS, visit National
