Silicon Image introduces SiI 7171
™
iTMDS (internal TMDS) receiver product for
high bandwidth needs of direct view LCD/plasma and rear projection (LCOS,
DLP, and LCD projection) digital televisions (DTVs), LCD monitors, and projectors.
While DVI 1.0 compliant for external applications, the SiI 7171 is ideal for internal
link of DTVs, monitors, and projectors. Innovative SiI 7171 architecture adds new
encoding method for high color depth support including 8, 10, 12, or 16 bits per
color. Silicon Image advance design technique allows single link SiI 7171 operation of
225MHz bandwidth. This allows SiI 7171 to support 720p/1080i/1080p resolution
with 12-bit per color at 60 Hz refresh rate. The SiI 7171 enables billions of color for
HDTVs, leading to exceptional digital visual quality.
SiI 7171 incorporates advanced automatic equalizer and PLL bandwidth for long
cable support and increase interoperability. Planned high definition content protec-
tion (HDCP) capable device with integrated pre-programmed keys provide secure
high definition video delivery at low cost. The SiI 7171 is available in a 128-LQFP
Universal environmentally friendly Pb free package.
Single link SiI 7171 provides bandwidth to support today’s 720p and tomorrow’s
1080p digital TVs at 8, 10, 12, or 16 bits per color using only four differential signal
pairs (three data pairs and one clock pair). Using today’s LVDS technology will
require two channel with up to 12 differential signal pairs. The SiI 7171 provides
significant cost savings for the digital TV internal interface by reducing the chip count
from two to one and dramatically reducing the cost of cable assembly by cutting
the number of wires needed.
Texas Instruments selects the SiI 7171 for 720p/1080p 10-bit Digital Light Projection
(DLP) reference design because it brings revolutionary solution to address the fast
growing band width of the digital TV internal interface while reducing overall bill of
material (BOM) cost.
