Abstract

Low-Voltage Differential Signaling (LVDS) is a new technology addressing the needs of today's high performance data transmission applications. The LVDS standard is becoming the most popular differential data transmission standard in the industry. This is driven by two simple features: "Gigabits @ milliwatts!" LVDS delivers high data rates while consuming significantly less power than competing technologies.

Description of Low Voltage Differential Signal


In addition, it brings many other benefits, which include:

a)Low-voltage power supply compatibility
b)Low noise generation


c)High noise rejection
d)Robust transmission signals


e) Ability to be integrated into system level ICs

LVDS technology allows products to address high data rates ranging from 100's of Mbps to greater than 2 Gbps. For all of the above reasons, it has been deployed across many market segments wherever the need for speed and low power exists.Consumers are demanding more realistic visual information in the office and in the home.

This drives the need to move video, 3D graphics and photo-realistic image data from cameras to PCs and printers through LAN, phone, and satellite systems to home set-top boxes and digital VCRs. Solutions exist today to move this high-speed digital data both very short and very long distances, on printed circuit boards (PCB) and across fiber or satellite networks.

Moving this data from board-to-board or box-to-box however, requires an extremely high-performance solution that consumes a minimum of power, generates little noise, (must meet increasingly stringent FCC/CISPR EMI requirements) is relatively immune to noise, and is cost-effective.
