Abstract :
A new videoprocessor IC featuring digital cut-off control loops requiring no storage capacitors, switchable cut-off measurement lines, and improved average beam current limitation has been developed. The IC provides the video bandwidth required for HDTV and double-scan TV sets. The videoprocessor has an onchip bus-interface and an 8×8 bit register to control all important functions of the circuit. The large number of fully integrated features allows the designer to build a video board with a minimum number of external components
