GENERAL DESCRIPTION
The SAA6713AH is a single input single-chip Thin Film
Transistor (TFT) display controller IC with analog VGA
standard input capabilities. Additionally, the SAA6713AH
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
incoming video mode and advanced auto-adjustment
features that provide all data for a fast and accurate
adjustmentoffrequency,phaseandgainsettings.Theunit
is 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
heighttofittotheconnectedpanelresolution.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
×
18 ROM font consisting of 179 ANSI characters,
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
×
8 and
32
×
32pixels.Another38 specialcharactersareprovided
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
×
8 to 32
×
32 pixels and up to four colours per
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 not only drive today’s common timing
controller based panel interfaces, but it has also the
capability to directly drive the row and column drivers of a
panel itself. An adjustable output pin ordering guarantees
easy board layout with any type of panel connector.
The SAA6713AH represents a fully integrated single-chip
solution for low-end monitors, offering both high quality
scaling and an advanced OSD generator.
