Low-voltage differential signaling, or
LVDS, also known as
TIA/EIA-644, is a technical standard that specifies electrical characteristics of a
differential,
serial communications protocol. LVDS operates at low power and can run at very high speeds using inexpensive
twisted-pair copper cables. Since LVDS is a physical layer specification only, many data communication standards and applications use it but then add a data link layer as defined in the
OSI model on top of it.
