It integrates a high quality Four windows font OSD with bordering / shadow 2D comb NTSC/PAL/SECAM video decoder, triple high Image Processing speed RGB ADCs, high quality scaler, and images enhancement functions which include Black and High quality scaler with both up/down and White Stretch and etc. It also supports panoramic nonlinear scaling support scaling for conversion to wide screen display. On the Built-in 2D de-interlacing function input side, it supports a rich combination of CVBS, S- Programmable hue, brightness, saturation, video. On the output side, it supports variety of digital contrast and sharpness panel types with its built-in timing controller. Supports programmable cropping of input video and graphics Features Independent RGB gain and offset controls Analog Video Decoder Panorama / Water-glass scaling NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), SECAM with automatic Programmable 10-bit Gamma correction for format detection each color Three 10-bit ADCs and analog clamping circuit Operated in Frame Sync mode Fully programmable static gain or automatic Black/White Stretch gain control for the Y or CVBS channel Clock Generation Programmable white peak control for the Y or Spread spectrum clock CVBS channel Modulation frequency and spread width are Software selectable analog inputs selectable High quality adaptive 2D comb filter for both Power Management NTSC and PAL inputs Supports functional based independent power PAL delay line for color phase error correction down Image enhancement with 2D dynamic peaking 1.8 / 3.3 V operation and CTI Miscellaneous Digital sub-carrier PLL for accurate color Supports 2-wire serial bus interface decoding Built-in single LED back light controller Digital horizontal PLL and Advanced synchronization processing for VCR playback Built-in VCOM DC voltage and weak signal performance Built-in VCOM analog amplitude Programmable hue, brightness, saturation, Built-in DC-DC convertor contrast and sharpness Single 27MHz crystal High quality horizontal and vertical filtered down 80-pin LQFP package scaling with arbitrary scale down ratio TFT Panel Support Applications Built-in programmable timing controller In-car display controller Supports 3, 4, 6 or 8 bits per pixel up to 16.8 Portable DVD and DVRs players million colors with built-in dithering engine Portable media player Support digital panel up to WVGA/SVGA resolution Support Serial (8bit) RGB panel On Screen Display FN7825 Rev. 1.00 Page 1 of 2 April 25, 2013 TW8831 FLAT PANEL OUT TCON SIGNALS TCON YIN0~2 FONT OSD SERIAL DATA 2D-COMB CIN LED/ INPUT VIDEO VCOM OUTPUT CONTROLLER DECODER VIN CONTROL Triple FORMATTER SCALER ADCs IMAGE I2C SDAT ENHANCE 2-WIRE SERIAL I2C SCLK BUS FUNCTIONAL BLOCK DIAGRAM Copyright Intersil Americas LLC 2011-2012.
