DATA SHORT To request the full datasheet, please visit www.intersil.com/products/TW8820 TW8820 FN8279 Rev. 1.00 April 24, 2014 LCD Controller Description The TW8820 incorporates many of the features required to create a multi-purpose Video Door phone intercom LCD display system in a single package. It integrates a high quality 2D comb NTSC/PAL/SECAM video decoder, high quality scaler, and image enhancement functions which include Black and White Stretch and Gamma Correction. It also supports panoramic scaling for conversion to wide screen display. TW8820 supports analog composite video input and the output supports a wide variety of digital LCD panel types with its built-in timing controller. Features ANALOG VIDEO DECODER  NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), SECAM with automatic format detection  10-bit ADC and analog clamping circuit TIMING CONTROLLER (TCON)  Supports programmable timing interface signals for control  Column (source) driver/row (gate) driver ON SCREEN DISPLAY  6912 byte programmable font RAM and 256 display RAM  Four windows font OSD with bordering/shadowing  1/2/3/4 bits/pixel  Supports variable width (12/16), height (2~32) IMAGE PROCESSING  High quality scaler with both up/down and nonlinear scaling support  Panorama/Water-glass scaling  Built-in 2D de-interlacing function  Programmable hue, brightness, saturation, contrast and sharpness  Fully programmable static gain or automatic gain control for the Y or CVBS channel  Programmable cropping of input video and graphics  Programmable white peak control for the Y or CVBS channel  Programmable 8-bit Gamma correction for each color  High quality adaptive 2D comb filter for both NTSC and PAL inputs  Black/White Stretch  Independent RGB gain and offset controls  Operates in Frame Sync mode  PAL delay line for color phase error correction CLOCK GENERATION  Image enhancement with 2D dynamic peaking and CTI  Spread spectrum clock  Digital sub-carrier PLL for accurate color decoding  Digital horizontal PLL and advanced synchronization processing for VCR playback and weak signal performance  Programmable hue, brightness, saturation, contrast and sharpness 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  Supports digital panels up to WVGA/SVGA resolution  Selectable Modulation frequency and spread width MCU  Industry standard 8052 based  Code fetch from external SPI flash memory  512 byte XDATA memory POWER MANAGEMENT  Supports functional based independent  Power-down  1.8/3.3V operation  Supports Serial (8-bit) RGB panels FN8279 Rev. 1.00 April 24, 2014 Page 1 of 2 TW8820 MISCELLANEOUS Applications  Supports 2-wire serial bus interface  Video door phone intercom display controller  Built-in Auxiliary ADC input  Portable DVD players, media players, and DVRs  Single 27MHz crystal  Rear Camera Displays  64 pin LQFP package SPI Flat Panel Out SPI YIN1~2 MCU TCON 2D-Comb Video Decoder Triple Triple Triple ADCs ADCs ADCs Serial Data Font OSD Input Controller TCON signals GPIO Scaler Image Enhance Output Formatter 2-Wire Serial Bus I2C_SDAT I2C_SCLK TW8820 FUNCTIONAL BLOCK DIAGRAM © Copyright Intersil Americas LLC 2012-2014.
