1162
PanelLink Transmitter
The SiI 1162 is a DVI-compliant transmitter incorporating next-
generation PanelLink
®
technology to support the full DVI bandwidth
of 25 to 165 MHz. As a result, the SiI 1162 supports LCD monitors
and projectors with resolutions that range from VGA to UXGA
(1600 x 1200). Three TMDS
TM
data channels for RGB send data at up
to 1.65 Gbps per channel. The SiI 1162 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 1162 is available in a low-cost, easier-to-use, 48-pin TSSOP
package with a 40% smaller footprint compared to other discrete
DVI transmitters. By incorporating the most advanced PanelLink DVI
technology available today, the SiI 1162 transmitter brings higher
performance and guaranteed compatibility to your DVI 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 1162, yield consistently
robust differential signal “eyes” that exceed the minimum “eye” width & height requirements of
the DVI specification at the full DVI bandwidth of 25-165 MHz.
