DATASHEET To request the full datasheet, please visit www.intersil.com/products/TW9919 5x10-bit Multi-standard 3D Comb Filter Video Processor with SCART and RGB Mixing Support TW9919 • IF compensation filter Techwell’s TW9919 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. TW9919 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 containing anti-aliasing filter, AGC, clamping, and five 10-bit high speed ADCs. For composite inputs, an adaptive comb filter and luma/chroma processing produce exceptionally high quality pictures using proprietary techniques. A high quality internal scaling engine offers arbitrarily filtered down scaling 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 14 analog input terminals allow maximum flexibility: • 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 • Up to six 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 • Power-down mode • Typical power consumption 0.6W • 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 • Programmable white peak control for the Y channel • 2.5V / 3.3V Power Supply • High quality analog RGB/YCbCr mixing by Fast Blanking signal 128 pin PQFP package • High quality motion adaptive 3D comb filter for both NTSC and PAL with concurrent 3D noise reduction • 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 and 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 control and color killer January 5, 2015 FN7774.0 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Copyright Intersil Americas LLC 2015.
