TW9906 uses the mixed-signal 2.5v/3.3v cmos technology to provide a low-cost and low-power integrated solution. minimum external components are required due to its integrated analog front-end contai ning anti-aliasing filter, agc, clamping, and three 10-bit high speed adcs. for composite inputs, an adaptive comb filt er and luma/chroma processing produce exceptionally high quality pictures using proprietary techniques. a high quality inte rnal scaling engine offers arbitrarily filtered down scalin g of the output video. its vbi capability is enhanced with built-in vbi slicer, filter, fifo and vbi data pass-through function to support common data services. features ? ntsc (m, 4.43) and pal (b, d, g, h, i, m, n, n combination), pal (60), secam support with automatic format detection ? advanced synchronization processing for vcr trick mode and weak signal ? software selectable analog inputs allows any of the following combinations: - up to five composite video inputs - four composite, one s-video or one ycbcr input. - two composite, two s-video or two ycbcr inputs. - three composite, one s-video and one ycbcr input. ? three 10-bit adcs with clamping circuit and anti-aliasing filter. ? fully programmable static or aut omatic gain control for the y channel ? programmable white peak co ntrol for the y channel ? adaptive 4h comb filter for the best image quality. ? pal delay line for color phase error correction ? digital sub-carrier pll for accurate color decoding ? digital horizontal pll an d advanced synchronization processing for non-standard video signals ? programmable hue, brightness, saturation, contrast, and sharpness ?blue stretch ? image enhancement with 2d peaking and cti. ? automatic color control and color killer ?if compensation filter ? detection of level of copy protection according to macrovision standard ? ycbcr input supports 480i/576i and sub-sampled 480p/576p with auto-detection. video output ? support both free-running and line-locked clock outputs ? programmable output cropping ? high quality horizontal filtered scaling with arbitrary scale down ratio ? vmi 1.4 compatible 10-bit or 20-bit pixel interface ? itu-r 601 or itu-r 656 compatible output ycbcr(4:2:2) output format ? vbi slicer supporting industrial standard data services with data packet filter capability ? built-in vbi fifo for convenient access through host interface ? vbi data pass through, raw adc data for intercast? ? field locked audio clock generator miscellaneous ? two wire mpu serial bus interface ? power-down mode ? typical power consumption 0.25w ? single 27mhz crystal for all standards ? supports 24.54mhz and 29.5mhz crystal for high quality square pixel format ?3.3v / 5v tolerant i/o ? 2.5v / 3.3v power supply ? 80 pin tqfp package
