The SAA6703H is a dual input single-chip Thin Film
Transistor (TFT) display controller IC with analog VGA and
digital DVI 1.0 standard input capabilities. Additionally, the
SAA6703H includes a wide range of functions for
processing and the measurement of incoming RGB data
according to the requirements of an XGA TFT display.
Covered functions are accurate measurements for the
horizontal and vertical input frequencies to determine the
(1) DVI specification published by Digital Display Working Group
(2) HDCP is software designed by Intel/Silicon Image. All

GENERAL DESCRIPTION
(1)
compliant digital serial interface up to 110 MHz

C-bus interface up to 3.4 Mbits/s

incoming video mode and advanced auto-adjustment
features that provide all data for a fast and accurate
adjustment of frequency, phase and gain settings. Both
units are able to generate interrupts for easy interfacing
with a system microcontroller with separately maskable
interrupt conditions.
The input section handles incoming data up to SXGA
resolution that can be downscaled individually in width and
height to fit to the connected panel resolution. Independent
horizontal and vertical upscaling with enhanced
programmable filter possibilities provides the IC’s core
functionality of high-quality scaling. Picture quality is
further supported by an enhanced colour management
including a 10-bit gamma correction function.
A sophisticated dithering unit allows the use of low-end
6-bit panels while keeping up the high quality image
impression.
An advanced OSD generator is integrated with a fixed
12
77 Japanese characters, 48 multicolour icons and
48 single colour icons. In addition to these fixed size
characters another 112 different border characters can be
generated in any desired font size between 8
32
particularly for multicolour slider icons that can be
parametrized in size and style. For higher flexibility of the
OSD appearance a downloadable mixed multicolour or
single colour font with any programmable character size
between 8
character can be used and displayed together with the
predefined ROM characters. A special bitmap organized
graphical OSD with up to 16 individual colours allows to
include graphic items like company logos, while a double
buffered OSD cursor gives the ability to use animated
pointers within an on screen menu. The panel timing
interface can drive today’s common timing controller
based panel interfaces. An adjustable output pin ordering
guarantees easy board layout with any type of panel
connector.
The SAA6703H represents the first fully integrated
single-chip solution for low-end monitors, offering both
high quality scaling and an advanced OSD generator.
