NOT RECOMMENDED FOR NEW DESIGNS DATA SHORT RECOMMENDED REPLACEMENT PART To request the full datasheet, please visit www.intersil.com/products/TW8804 TW8835 (Not Pin Compatible) TW8804 FN7756 Rev.0.00 LCD Flat Panel TV/PC Monitor Controller with built-in NTSC/PAL/SECAM February 1, 2011 Decoder and Analog RGB/FB Input The TW8804 LCD Flat Panel Controller is a low cost high Features quality TFT panel controller with an embedded Low angle compensation circuit for smooth video rendering NTSC/PAL/SECAM TV decoder. This unique level of mixed signal integration enables the panel to be used as a Black/White/Blue stretch for higher contrast stand-alone analog TV. An integrated YPbPr/RGB component Sharpness control for sharper video input allows direct connection to DVD, PIP and TTX sources. Panorama/water glass feature for more natural scaling Separate digital inputs allow it to be used as a high quality computer monitor when combined with additional ICs. It Integrated OSD with 200+ user defined fonts incorporates easy-to-operate and powerful features in a single Integrated programmable timing controller (TCON) package for LCD TV,multi-purpose LCD Monitor, Portable DVD Players and Car Display Entertainment Systems. TFT Panel Support The TW8804 contains all the logic required to convert Supports a wide variety of active matrix TFT panels either standard TV, DTV, and PC monitor signals to the digital control one or two pixels per clock and data signals required to drive various TFT panel types. It Supports panel with resolution up to SXGA (1280 x 1024) supports TFT panel resolutions up to 1280 by 1024 (SXGA/WXGA) with either 1 or 2-pixel/clock formats. Timing Controller (TCON) The chip accepts CVBS (composite) analog input or S-video Support programmable interface signals for control column analog input or YPbPr input for use as a video monitor. Up to (source) driver / row (gate) driver four physical CVBS inputs or one S-video input or one component input can be connected synchronously with Analog Video Decoder component (RGB or YPbPr) input via fast blanking and NTSC (M, 4.34) and PAL (B,D,G,H, I,M,N,N combination), PAL switched internally under external microprocessor control. (60),SECAM with automatic format detection The integrated analog front-end contains six ADCs with five Advanced synchronization processing for VCR fast forward, clamping circuits and one Automatic Gain Control (AGC) circuit backward, and pause mode to minimize external component count. It employs a 2/4H, 5- Six 9-bit ADCs and analog clamping circuit line adaptive comb filter and proprietary Y/C processing technologies to produce exceptionally high quality pictures. Fully programmable static gain or automatic gain control for the Y or CVBS channel The chip s internal logic synchronizes the panel frame rate to the incoming input frame rate. A high quality image-scaling 24bit Digital RGB and 8/16/24-bit YCbCr engine is used to convert the lower resolution formats or high Inputs resolution DTV formats to the output panel resolution. An internal de-interlacing engine also allows interlaced video to be Allows connection to analog PC Graphics cards with the supported. addition of a 3 channel A/D converter for up to SXGA resolution On Screen Display is supported through either external OSD chip or onchip OSD RAM for maximum flexibility. A Closed Allows YCbCr digital component input for DTV 480p, 720p, Caption decoder is built in. The TW8804 also accepts a 24 bit 1080i digital RGB input from external PanelLinkTM receiver or ADCs for use as computer monitor. In addition, it accepts 8/16/24 Image Control bits digital YCbCr input for use with external ADCs for use as a Programmable hue, brightness, saturation, contrast DTV monitor. Automatic color control and color killer The TW8804 also supports TFT panel power sequencing, Sharpness control with vertical peaking up to +12db DPMS Display Power Management Signaling) signaling and Programmable color transient improvement control power management. The control interface is a 2-wire serial bus interface. The TW8804 core operates at 2.5V, the IO at Supports programmable cropping of input video and 3.3V and is packaged in a 160-pin PQFP package. graphics High quality expansion for low-resolution graphics Built-in de-interlacing engine with proprietary low angle compensation circuit for smooth video rendering FN7756 Rev.0.00 Page 1 of 2 February 1, 2011TW8804 Features (Continued) Video Processing 4-H adaptive comb filter Y/C separation On Screen Display PAL delay line for color phase error correction Built-in OSD controller with integrated character ROM and Image enhancement with 2D dynamic peaking and CTI programmable RAM font Digital sub-carrier PLL for accurate color decoding Supports dedicated port for an optional external OSD controller Digital Horizontal PLL and advanced synchronization processing for non-standard video signals Programmable hue, brightness, saturation, contrast, sharpness, gamma control, and noise suppression Applications LCD TV LCD Monitor with TV Car TV Portable DVD Players CIN OSD YIN0 YIN1 YIN2 YIN3 YIN4 Alpha Blending YOUT DECHS DECVS FPR0 7:0 FPG0 7:0 FPB0 7:0 FPR1 7:0 FB0 FPG1 7:0 FB1 FPB1 7:0 RIN0 FPVS RIN1 FPHS GIN0 FPDE GIN1 FPCLK FPPWC BIN0 BIN1 Panel Timing FPBIAS Generator VCOM VREFN VREFP MC SDA DTVCLK Input Format 2 Wire MC SCL DTVVS Registers Measurement Serial Bus MC SIA DTVHS DTVDE DTVD 23:0 COAST FIGURE 1.
