The SiI 851 is a single-chip solution that provides all the necessary functions
required for a high-end pure digital SXGA or XGA flat panel monitor. As a
single-chip solution, the SiI 851 lowers overall cost, increases reliability,
requires less board space, and makes design and layout easier. The SiI 851
has an integrated PanelLink
Digital receiver, a programmable On-Screen-
Display (OSD) block, a clock multiplier, power management capabilities and a
number of high-quality PixelPrecision
TM
image processing features including:
Scaling, Dithering, Gamma Tuning, Color Temperature and Contrast Control.
The SiI 851 enables monitor designers to deliver the highest image quality,
Digital Visual Interface (DVI)-compliant monitors at costs low enough for
mass-market adoption. Additionally the SiI 851's new PixelPrecision image
processing features allows monitor designers to optimize a monitor's color
quality for any SXGA or XGA resolution panel. The SiI 851's programmable
panel interface is designed to work with all SXGA and XGA resolution LCD
panels, with fully customizable OSD functions that can localize monitors for
specific regions or market segments.

Silicon Image's
SiI 851 Starter Kit
(CP851DVI) enables easy demonstration
and evaluation of the Si
I 851 PanelLink
Controller. The starter kit includes all of
the hardware, software and documentation
necessary to set up a high performance
DVI-compliant monitor using Silicon
Image's Si
I 851. The SiI 851's registers
and configuration EEPROM, as well as the
EDID on the Si
I 851 development board,
can be programmed and read in real time
through a serial port. The printed circuit
board schematics, sample firmware,
configuration files and application notes
are provided as references so that new
designs easily incorporate the SiI 851.
