Product Summary

The TDA9381PS/N1/3S033 is a display processor for High-end television receiver which contains the following functions: RGB control processor with Y, U and V inputs, a linear RGB input for SCART or VGA signals with fast blanking, a linear RGB input for OSD and text signals with a fast blanking or blending option and an RGB output stage with black current stabilization, which is realized with the CCC (2-point black current measurement) system. Programmable deflection processor with internal clock generation, which generates the drive signals for the horizontal, East-West (E-W) and vertical deflection. The TDA9381PS/N1/3S033 has various features that are attractive for the application of 16: 9 picture tubes. The circuit can be used in both single scan (50 or 60 Hz) and double scan (100 or 120 Hz) applications.
