Renesas Electronics Corporation LCD Flat Panel Controller with Integrated NTSC/PAL/SECAM Decoder and Analog/Digital RGB/FB Input TW8804-LC3-GRSHT

The TW8804 LCD Flat Panel Controller is a low cost high quality TFT panel controller with an embedded NTSC/PAL/SECAM TV decoder. This unique level of mixed signal integration enables the panel to be used as a stand-alone analog TV. An integrated YPbPr/RGB component input allows direct connection to DVD, PIP and TTX sources. Separate digital inputs allow it to be used as a high quality computer monitor when combined with additional ICs. It incorporates easy-to-operate and powerful features in a single package for LCD TV,multi-purpose LCD Monitor, Portable DVD Players and Car Display Entertainment Systems.brbr The TW8804 contains all the logic required to convert standard TV, DTV, and PC monitor signals to the digital control and data signals required to drive various TFT panel types. It supports TFT panel resolutions up to 1280 by 1024 (SXGA/WXGA) with either 1 orbr2-pixel/clock formats.brbr The chip accepts CVBS (composite) analog input or S-video analog input or YPbPr input for use as a video monitor. Up to four physical CVBS inputs or one S-video input or one component input can be connected synchronously with component (RGB or YPbPr) input via fast blanking and switched internally under external microprocessor control.brbr The integrated analog front-end contains six ADCs with five clamping circuits and one Automatic Gain Control (AGC) circuit to minimize external component count. It employs a 2/4H, 5-line adaptive comb filter and proprietary Y/C processing technologies to produce exceptionally high quality pictures.brbr The chip's internal logic synchronizes the panel frame rate to the incoming input frame rate. A high quality image-scaling engine is used to convert the lower resolution formats or high resolution DTV formats to the output panel resolution. An internal de-interlacing engine also allows interlaced video to be supported.brbr On Screen Dis
