DATASHEET To request the full datasheet, please visit www.intersil.com/products/TW8832A2 TFT Display Controller TW8832A2, TW8832SA2 Applications - In-car display controller Portable DVD and DVRs players Portable media player Analog RGB Inputs Triple high speed 10-bit ADCs with clamping and programmable gain amplifier. SOG and H/V sync support for YPbPr or RGB input Description Built-in line locked PLL with sync separator The TW8832A2 incorporates many of the features required to create multi-purpose in-car LCD display system in a single package. It integrates a high quality 2D comb NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs, high quality scaler, and images enhancement functions which include Black and White Stretch and etc. It also supports panoramic scaling for conversion to wide screen display. On the input side, it supports a rich combination of CVBS, S-video, analog RGB as well as digital inputs. On the output side, it supports variety of digital panel types with its built-in timing controller. Support analog input resolution up to 1080i or WXGA Digital Inputs Support Support 656 video formats TFT Panel Support Built-in programmable timing controller Supports 3, 4, 6 or 8 bits per pixel up to 16.8 million colors with built-in dithering engine Support digital panel up to WVGA/SVGA resolution Support Serial (8-bit) RGB panel On Screen Display 256 programmable font RAM and 384 display RAM. Analog Video Decoder NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), SECAM with automatic format detection Three 10-bit ADCs and analog clamping circuit Fully programmable static gain or automatic gain control for the Y or CVBS channel Programmable white peak control for the Y or CVBS channel Software selectable analog inputs High quality adaptive 2D comb filter for both NTSC and PAL inputs PAL delay line for color phase error correction Four windows font OSD with bordering / shadow Supports bit-mapped based OSD through SPI (TW8832SA2 only) Image Processing High quality scaler with both up/down and nonlinear scaling support Built-in 2D de-interlacing function Programmable hue, brightness, saturation, contrast and sharpness Supports programmable cropping of input video and graphics Independent RGB gain and offset controls Panorama / Water-glass scaling Image enhancement with 2D dynamic peaking and CTI Programmable 10-bit Gamma correction for each color Digital sub-carrier PLL for accurate color decoding Operated in Frame Sync mode Digital horizontal PLL and Advanced synchronization processing for VCR playback and weak signal performance Black/White Stretch Programmable hue, brightness, saturation, contrast and sharpness Modulation selectable Clock Generation Spread spectrum clock frequency and spread width are High quality horizontal and vertical filtered down scaling with arbitrary scale down ratio August 16, 2011 FN7782.1 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Copyright Intersil Americas Inc. 2011.
