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. 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.
