PanelLink Transmitter
The SiI 1172 is the world’s first single-link TMDS
™
transmitter to
break the bandwidth barrier and support an amazing 225 MHz band-
width. The latest addition to SiI’s comprehensive SiI 1000 family of
DVI solutions, the SiI 1172 transmitter incorporates next-generation
PanelLink
®
technology to support bandwidths of 25 to 225 MHz.
As a result, the SiI 1172 supports LCD monitors and projectors
with resolutions that range from VGA to QXGA (2048 x 1536).
Three TMDS data channels for RGB send data at up to 2.25 Gbps
per channel. The SiI 1172 incorporates an industry-standard 12-bit
(1/2 pixel per clock edge) interface for true color (16.7 million)
support. Built-in flexibility enables customers to use pins to configure
settings or the I
2
C interface to program registers.
The SiI 1172 is available in a low-cost, easier-to-use, 48-pin TSSOP
package with a 57 % smaller footprint compared to other discrete
DVI transmitters. By incorporating the most advanced PanelLink
DVI technology available today, the SiI 1172 transmitter brings higher
performance and guaranteed compatibility to single-link DV I
applications while enabling faster time to market, smaller form
factor designs and lower system costs.
DVI-compliant Quality
The DVI 1.0 specification defines the precise system-level signaling at the output of a DVI
transmitter system and at the input of a DVI receiver system. As a result, any DVI-compliant
host will always interoperate with any DVI-compliant display. The most comprehensive
method to determine the quality and compliance of a DVI transmitter is to measure the
TMDS “eye” diagram as defined by the DVI 1.0 specification and the DVI Test & Measurement
Guide. Only high-performance PanelLink DVI transmitters, such as the SiI 1172, yield
consistently robust differential signal “eyes” that exceed the minimum “eye” width & height
requirements of the DVI specification throughout the full DVI bandwidth of 25-165 MHz.
At bandwidths above 165 MHz, the SiI 1172 is interoperable with PanelLink receivers also
rated to run over 165 MHz.
