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 × 32 pixels. Another 38 special characters are provided 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 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 SAA6703AH represents a fully integrated single-chip solution for low-end monitors, offering both high quality scaling and an advanced OSD generator. The SAA6703AH is a single input single-chip Thin Film Transistor (TFT) display controller IC with analog VGA standard input capabilities. Additionally, the SAA6703AH 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 adjustment of frequency, phase and gain settings. The unit is able to generate interrupts for easy .
