11 Facts About LVDS

LVDS operates at low power and can run at very high speeds using inexpensive twisted-pair copper cables.

LVDS is a physical layer specification only; many data communication standards and applications use it and add a data link layer as defined in the OSI model on top of it.

LVDS was introduced in 1994, and has become popular in products such as LCD-TVs, in-car entertainment systems, industrial cameras and machine vision, notebook and tablet computers, and communications systems.

LVDS is a differential signaling system, meaning that it transmits information as the difference between the voltages on a pair of wires; the two wire voltages are compared at the receiver.

The LVDS receiver is unaffected by common mode noise because it senses the differential voltage, which is not affected by common mode voltage changes.

Applications for LVDS expanded to flat panel displays for consumer TVs as screen resolutions and color depths increased.

LVDS does not specify a bit encoding scheme because it is a physical layer standard only.

The key point in LVDS is the physical layer signaling to transport bits across wires.

The difference from standard LVDS transmitters was increasing the current output in order to drive the multiple termination resistors.

Present form of LVDS was preceded by an earlier standard initiated in Scalable Coherent Interface .

Today, technologies for broadband digital video signal transmission such as LVDS are used in vehicles, in which the signal transmitted as a differential signal helps for EMC reasons.
