TDA9183

INTEGRATED CIRCUITS DATA SHEET TDA9183 Integrated NTSC comb filter Objective specification Supersedes data of 2000 Nov 22 File under Integrated Circuits, IC02 2000 Nov 30 Philips Semiconductors Objective specification Integrated NTSC comb filter FEATURES One-chip NTSC adaptive comb filter Cross luminance reduction Cross colour reduction No chroma trap, therefore sharper vertical luminance transients Analog discrete-time signal processing, therefore no quantization noise Anti-aliasing and reconstruction filters are included Input switch selects between two Y/CVBS inputs Output switch selects between combed CVBS and an external Y/C source fSC as well as 2 × fSC colour subcarrier signal may be applied Alignment free Few external components Low power.
