Rev 3.00
July 26, 2016 Low Cost Video Format Converter
The TW8809 is a low cost video format converter that can take
either analog CVBS or 24-bit digital RGB format video and
output these signals in ITU-R.656 format. The video sources
can be scaled and deinterlaced, so that the ITU-R BT.656
output is already formatted to the desired resolution and in
progressive format. In addition, the TW8809 has built-in OSD
and image enhancement capabilities. On Screen Display Applications Image Processing Rear seat entertainment Radio head unit Features 256 font RAM and 512 display RAM Four windows font OSD with bordering/shadowing 1/2/3/4 bits/pixel Supports variable width (12/16), height (2~32) High quality scaler with both up/down and nonlinear scaling
support Panorama/water-glass scaling Built-in 2D deinterlacing function Analog Video Decoder Programmable hue, brightness, saturation, contrast and
sharpness NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination),
PAL (60), SECAM with automatic format detection Programmable cropping of input video and graphics Selectable differential or single-ended CVBS input Supports two differential or 4 single-ended CVBS inputs 10-bit ADC and analog clamping circuit Fully programmable static gain or automatic gain control for
the Y or CVBS channel Independent RGB gain and offset controls Programmable 8-bit Gamma correction for each color Operates in frame sync mode Black/white stretch Clock Generation Programmable white peak control for the Y or CVBS channel Spread spectrum clock High quality adaptive 2D comb filter for both NTSC and PAL
inputs Selectable modulation frequency and spread width PAL delay line for color phase error correction Power Management Image enhancement with 2D dynamic peaking and CTI Supports functional based independent power-down Digital subcarrier PLL for accurate color decoding 1.8/3.3V operation Digital horizontal PLL and advanced synchronization
