Low-Voltage Differential Signaling (LVDS) is a technology addressing the needs of today’s high performance data transmission applications. LVDS is an electrical system and can run at very high speeds over inexpensive, twisted-pair, stranded copper cables. These twisted pairs maintain the 100ohm differential impedance required by LVDS data signals. LVDS has become a preferred differential standard due to its capability of delivering high data rates while consuming less power than any other interfacing technologies. LVDS uses high-speed analog circuit techniques to provide multi gigabit data transfers on copper interconnects and is a generic interface standard for high-speed data transmission. This is why the LVDS standard is becoming the most popular differential data transmission standard in the industry.
What are LVDS Cables Used For?
LVDS cables are the best choice where low power exists and a large amount of data transfer is required. The main application of LVDS systems and cables is in computers. Before LVDS cable assemblies were introduced, the data transfer rate was too slow and cables used to occupy more space.
LVDS is now supported by SCSI standards. This allows cable assemblies built for LVDS to support higher data rates and longer cable lengths.
LVDS cable assemblies are also used in video interfacing devices. They are more commonly used for transporting video data from graphics adapters to computer monitors, particularly LCD screens, FPD-Link or OpenLDI standards. These standards of LVDS cable assemblies allow a maximum pixel clock of 112 MHz, which suffices for a display resolution of 1400 x 1050 (SXGA+) at 60 Hz refresh. A dual link can boost the maximum display resolution to 2048 x 1536 (QXGA) at 60 Hz. FPD-Link works with cable lengths up to about 5 m, and LDI extends this to about 10 m.
What are the Benefits of LVDS Cables?
LVDS cables are very popular in electronic communication devices like computers. These cables are of great use in networking as well as in analog video interfacing. The length of data transfer cable assembly can be from 1.00 inch to several meters (6-7) depending on the structure and requirement of the LVDS system.
The benefits of LVDS include:
- Compatible to low-voltage power supply
- Low noise generation
- High noise rejection
- Robust transmission signals
- Ability to be integrated into system level ICs
