fn7772 rev.0.00 feb 11, 2011 TW9909 5x10-bit multi-standard 3d comb filter video processor with sca rt and rgb mixing support data short fn7772 rev.0.00 page 1 of 2 feb 11, 2011 to request the full datasheet, please visit www.intersil.com/products/TW9909 techwell?s TW9909 is a high performance ntsc/pal/secam multi-standard 10-bit video decoder plus scart/ycbcr component inputs and analog rgb overlay support designed for multimedia applications. TW9909 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 five 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 the main features of the TW9909 are ? 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 14 analog input terminals allow maximum flexibility: ? up to five composite, or two s-video or two ycbcr inputs ? up to two scart rgb inputs with fb. ? five 10-bit adcs with clamping circuit and anti-aliasing filter built-in ? fully programmable static or automatic gain control for the y and g(y) channel ? programmable white peak control for the y channel ? high quality analog rgb/ycbcr mixing by fast blanking signal ? 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 function ? image enhancement with 2d peaking and cti. ? automatic color cont rol 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 ? 10-bit or 20-bit output 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 0.4w ? 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 not recommended for new designs no recommended replacement contact our technical support center at 1-888-intersil or www.intersil.com/tsc
