| GENESIS MICROCHIP S9255 Product Brief C9255-PBR-01B September 2002 DVI Interface with TCON Display Processor PRODUCT HIGHLIGHTS * * * * * * * * * * * * * * * * * * * * * * DVI-compliant 135 MHz receiver High bandwidth digital content protection CCIR 656 compatible 8 bit video port Intelligent Picture ProcessingTM Video window detection SureSyncTM and AutoAdjustTM Stand-alone test pattern generator Supports input & panel resolutions up to SXGA Integrated Microcontroller Programmable multi tap poly phase advanced scaling engine Five zone variable scaling - Ideal for WXGA panels Programmable regional scaling coefficients Edge enhancement in 1:1 mode Supports zoom and shrink scaling ACM IITM (Second Generation Active Color ManagementTM) Dual Gamma Table Correction Back light intensity control through PWM Adaptive Backlight ControlTM Adaptive Contrast control TM Flexible OSD Engine with 8 Kbytes of OSD Memory Adaptive flicker Rate Control Fail-safe display mode for high refresh inputs DESCRIPTION The Genesis S9255 is a highly integrated, feature-rich digital input LCD monitor controller targeted at SXGA resolution monitors. It inputs DVI-compliant signals and will perform advanced image processing to ensure the best display on a TFT LCD Monitor. It features an advanced scaling architecture with five zone variable scaling and edge enhancement capabilities in the native resolution modes. A programmable poly phase filter ensures smooth natural images and enhanced sharper text to provide excellent image quality. A proprietary video window detection algorithm detects coordinates of any video data overlayed on the image. The flexible scaling architecture also allows programmable scaling coefficients in either a defined region or on the entire screen. A state of the art and industryfirst Adaptive Color and Contrast (ACC) along with the Auto Backlight Level Control (ABL) ensure excellent viewing quality for both static and dynamic images. S9255 has second generation Active Color Management TM. This technology provides accurate flesh tone compensation, color space conversion and hue / saturation control over either a programmable window or the entire screen. Dual 10 - bit color look up tables allow independent gamma control for a programmable window and the background image. Integration of a state of the art 135 MHz DVI receiver, industry's best scalar and a host of other advanced features for video and color control make the S9255 an excellent solution for DVI monitors.
