It DIGITAL INPUTS SUPPORT integrates a high quality 2D comb NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs, high Supports BT.656 video formats quality scaler, and images enhancement functions which include Black and White Stretch and Gamma TFT PANEL SUPPORT Correction. It also supports panoramic scaling for conversion to wide screen display. The TW8830 Built-in programmable timing controller supports a rich combination of inputs: CVBS, S-video, Supports 3, 4, 6 or 8 bits per pixel up to 16.8 analog RGB as well as digital BT.656. On the output million colors with built-in dithering engine side, it supports a wide variety of digital panel types Supports digital panel up to WVGA/SVGA resolution with its built-in timing controller. Supports Serial (8-bit) RGB panel Features ON SCREEN DISPLAY 6912 byte programmable font RAM and 256 ANALOG VIDEO DECODER display RAM NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N Four windows font OSD with bordering / shadowing combination), PAL (60), SECAM with automatic 1/2/3/4 bits/pixel format detection Supports variable width (12/16), height (2~32) Three 10-bit ADCs and analog clamping circuit Fully programmable static gain or automatic gain IMAGE PROCESSING control for the Y or CVBS channel High quality scaler with both up/down and Programmable white peak control for the Y or CVBS nonlinear scaling support channel Panorama / Water-glass scaling Software selectable analog inputs Built-in 2D de-interlacing function High quality adaptive 2D comb filter for both NTSC and PAL inputs Programmable hue, brightness, saturation, contrast and sharpness PAL delay line for color phase error correction Programmable cropping of input video and graphics Image enhancement with 2D dynamic peaking and CTI Independent RGB gain and offset controls Digital sub-carrier PLL for accurate color decoding Panorama / Water-glass scaling Digital horizontal PLL and Advanced Programmable 8-bit Gamma correction for each synchronization processing for VCR playback and color weak signal performance Operated in Frame Sync mode Programmable hue, brightness, saturation, contrast Black/White Stretch and sharpness CLOCK GENERATION High quality horizontal and vertical filtered down scaling with arbitrary scale-down ratio Spread spectrum clock ANALOG RGB INPUTS Modulation frequency and spread width are selectable Triple high speed 10-bit ADCs with clamping and programmable gain amplifier.
