DATA SHORT To request the full datasheet, please visit www.intersil.com/products/TW8824 TW8824 FN8667 Rev 1.00 LCD Video Processor with Built-in Decoder, TTL Inputs, BT.656 Output and LVDS February 26, 2015 Panel Interface The TW8824 is a highly integrated LCD video processor that Features incorporates many of the key features required to create a multipurpose LCD display system into a single package. This Analog Video Decoder includes a high quality 2D comb NTSC/PAL/SECAM video NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), decoder, which supports both single-ended and differential PAL (60), SECAM with automatic format detection CVBS signals, a digital RGB input interface, high quality scaler and deinterlacer, a Font OSD engine and LVDS, TTL or TCON 10-bit ADC and analog clamping circuit output panel interfaces. The TW8824 can support input Fully programmable static gain or automatic gain control for resolutions up to 1080p and can drive LCD panels at CVBS channel resolutions up to 1366x768. The TW8824s video processing Programmable white peak control for the CVBS channel capability includes arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment and enhancement, black High quality adaptive 2D comb filter for both NTSC and PAL and white stretch, etc. This device can support fast boot inputs system requirements and provides stability and reliability to PAL delay line for color phase error correction the system due to the fact that it is a hardwired solution that can sync to the video source and display an image on the LCD Image enhancement with 2D dynamic peaking/CTI in less than 0.5 seconds from start-up. The feature set and Digital sub-carrier PLL for accurate color decoding versatility of this device makes it an ideal solution for in-car Programmable hue, brightness, saturation, contrast, LCD display applications. sharpness Selectable differential or single-ended CVBS input Applications Digital horizontal PLL and advanced synchronization Automotive display systems processing for VCR playback and weak signal performance High quality horizontal and vertical filtered down scaling with arbitrary scale down ratio Up to 3-CH differential or 6-CH single-ended CVBS input FIGURE 1.
