DATA SHORT To request the full datasheet, please visit www.intersil.com/products/tw8809 TW8809 FN8598 Rev 3.00 Low Cost Video Format Converter July 26, 2016 The TW8809 is a low cost video format converter that can take On Screen Display either analog CVBS or 24-bit digital RGB format video and 256 font RAM and 512 display RAM output these signals in ITU-R.656 format. The video sources Four windows font OSD with bordering/shadowing can be scaled and deinterlaced, so that the ITU-R BT.656 output is already formatted to the desired resolution and in 1/2/3/4 bits/pixel progressive format. In addition, the TW8809 has built-in OSD Supports variable width (12/16), height (2~32) and image enhancement capabilities. Image Processing Applications High quality scaler with both up/down and nonlinear scaling Rear seat entertainment support Radio head unit Panorama/water-glass scaling Built-in 2D deinterlacing function Features Programmable hue, brightness, saturation, contrast and Analog Video Decoder sharpness NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), Programmable cropping of input video and graphics PAL (60), SECAM with automatic format detection Independent RGB gain and offset controls Selectable differential or single-ended CVBS input Programmable 8-bit Gamma correction for each color Supports two differential or 4 single-ended CVBS inputs Operates in frame sync mode 10-bit ADC and analog clamping circuit Black/white stretch Fully programmable static gain or automatic gain control for the Y or CVBS channel Clock Generation Programmable white peak control for the Y or CVBS channel Spread spectrum clock High quality adaptive 2D comb filter for both NTSC and PAL Selectable modulation frequency and spread width inputs Power Management PAL delay line for color phase error correction Supports functional based independent power-down Image enhancement with 2D dynamic peaking and CTI 1.8/3.3V operation Digital subcarrier PLL for accurate color decoding Digital horizontal PLL and advanced synchronization Miscellaneous processing for VCR playback and weak signal performance Short-to-battery detection test Programmable hue, brightness, saturation, contrast and Short-to-ground detection test sharpness Supports 2-wire serial bus interface Digital Input Single 27MHz crystal Supports YCbCr/RGB 24-bit input 56 lead QFN (with wettable flanks) Supports both BT.656 and BT.601 video formats TW8809AT-NA2-GR is AEC-Q100 qualified Supports input resolutions up to 720p Digital Output ITU-R BT.656 compatible YCbCr (4:2:2) output format Progressive ITU-R BT.656 output format for both interlaced and progressive inputs Output resolution up to SVGA (pseudo BT.656) FN8598 Rev 3.00 Page 1 of 2 July 26, 2016INMUX MUX TW8809 TW8809 Functional Block Diagram YIN0+/YIN0 YIN0/YIN1 10bit 2DComb AAF YIN2+/YIN2 ADC Decoder YIN2/YIN3 Scaler BT.656 Gamma OUT BT.656 ImageEnhancer CSC Dither MUX Encoder TimingGen.
