TRIPLE 10-BIT LVDS TRANSMITTER FOR VIDEO
General Description
The V103A LVDS display interface transmitter is
primarily designed to support pixel data transmission
between a video processing engine and a digital video
display. The data rate supports up to SXGA+
resolutions and can be used in Plasma, Rear Projector,
Front Projector, CRT and LCD display applications. It
can also be used in other high-bandwidth parallel data
applications and provides a low EMI interconnect over
a low cost, low bus width cable up to several meters in
length.
The V103A converts 35 bits of CMOS/TTL data,
clocked on the rising or falling edge of an input clock
(selectable), into six LVDS (Low Voltage Differential
Signaling) serial data stream pairs. In video
applications the 35 bits is normally divided into 10 bits
for each R, G and B channel and 5 control bits.
When combined with the V104 LVDS display interface
receiver, the V103A + V104 combination provides a
35-bit wide, 90 MHz transport. The rate of each LVDS
channel is 630 Mbps for a 90MHz data input clock, 945
Mbps for 135MHz.
