DATA SHORT To request the full datasheet, please visit www.intersil.com/products/TW8832 TW8832, TW8832S FN7855 Rev. 4.00 May 6, 2014 TFT Display Controller Description The TW8832 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, etc. It also supports panoramic scaling for conversion to wide screen display. On the input side, it supports a rich combination of CVBS, Svideo, analog RGB as well as digital inputs. On the output side, it supports a variety of digital panel types with its built-in timing controller. Applications  In-car display controller  Portable DVD and DVRs players 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  Built-in line locked PLL with sync separator  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  Portable media player On Screen Display Features  256 programmable font RAM and 384 display RAM Analog Video Decoder  Supports bit-mapped based OSD through SPI (TW8832S only)  NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), SECAM with automatic format detection  Four windows font OSD with bordering / shadow Image Processing  Three 10-bit ADCs and analog clamping circuit  High quality scaler with both up/down and nonlinear scaling support  Fully programmable static gain or automatic gain control for the Y or CVBS channel  Built-in 2D de-interlacing function  Programmable white peak control for the Y or CVBS channel  Programmable hue, brightness, saturation, contrast and sharpness  Software selectable analog inputs  Supports programmable cropping of input video and graphics  High quality adaptive 2D comb filter for both NTSC and PAL inputs  Independent RGB gain and offset controls  PAL delay line for color phase error correction  Image enhancement with 2D dynamic peaking and CTI  Digital sub-carrier PLL for accurate color decoding  Digital horizontal PLL and Advanced synchronization processing for VCR playback and weak signal performance  Panorama/Water-glass scaling  Programmable 10-bit Gamma correction for each color  Operated in Frame Sync mode  Black/White Stretch  Programmable hue, brightness, saturation, contrast and sharpness  High quality horizontal and vertical filtered down scaling with arbitrary scale down ratio FN7855 Rev. 4.00 May 6, 2014 Page 1 of 3 TW8832, TW8832S Clock Generation  Spread spectrum clock  Modulation frequency and spread width are selectable Power Management  Supports functional based independent power down  1.8/3.3 V operation Miscellaneous  Supports 2-wire serial bus interface  Built-in single LED back light controller  Built-in VCOM DC voltage  Built-in VCOM analog amplitude  Built-in DC-DC convertor  Single 27MHz crystal  80-pin LQFP package SPI Flat Panel Out YIN0~2 2D-Comb CIN Video Decoder VIN SPI OSD Font OSD Input Controller Triple Triple Triple ADCs ADCs ADCs TCON signals Serial Data Output Formatter Image Enhance DTVCLK DTVD[7:0] Scaler TCON BT656 I/F LED/ VCOM Control 2-Wire Serial Bus I2C_SDAT I2C_SCLK FIGURE 1.
