What are LVDS Interface ICs?

An LVDS (Low Voltage Differential Signalling) interface circuit is a semiconductor device that can provide a balanced transmission method. They can operate at low power, and by using copper cables, they can run at high speeds too.

It has gradually become popular in automotive infotainment, LCD television sets, machine vision, communication systems, etc. 

Types

The LVDS interface ICs are available in different types, each having a separate specification. These include:

LVDS Serialiser and deserialiser

The serialiser can convert the parallel data into a serial, high-speed LVDS stream of data. The deserialiser can take a serial output of the serialiser and then convert it back to parallel. 

LVDS transmitters

The LVDS transmitter ICs can apply a continuous voltage current into the wires. The current direction can determine the digital logic.

LVDS receivers

These devices can implement the attributes of the LVDS. Some of the receivers can feature ultra-low power consumption levels. It can also accomplish the separation of input and output signals and the flowthrough pin configuration for easier laying onto a PCB.

LVDS buffer

The LVDS buffer is also known as a fanout buffer. It can create several copies of the input signal and then disseminate among the different loads while ensuring low jitter and faster rise or fall times.

LVDS repeaters

These repeaters can provide for the separation of the input and output signals. It can be done using the LVDS technique. The devices can accept a single LVDS input and then duplicate the signal.

Applications

These LVDS interface ICs have several applications, inluding:

• P2P data transmission
• High-speed video
• Infrastructure for wireless base station 
• Backplane data transmission
• Graphics
