Product Summary

The BT252KPJ20 is a image digitizer designed to digitize standard video signals. The architecture of the BT252KPJ20 enables the addition of external circuitry for such functions as filtering and gain along the signal path. A standard MPU interface is provided to access various control functions. The applications of the BT252KPJ20 include image processing, image capture, desktop publishing and graphic art systems.
