HDTV ANTIALIASING FILTERS
ZERO LOSS
• • • Zero Insertion loss • Fully compliant to SMPTE 260M Low output impedance via op-amp driver stage • pin DIP package Integer multiple clock delay between luminance and chrominance filters
Meeting all the pre and post filtering characteristics of SMPTE 260M this range of HDTV antialiasing filters include a video buffer to give 0dB insertion loss. This more complete and accurate solution removes some of the ambiguity of optimising buffers and filters separately particularly illustrated at the high bandwidths required for HDTV applications.
