DEFLECTION PROCESSOR FOR MULTISYNC MONITORS

DEFLECTION PROCESSOR

The KB2512 is a monolithic integrated circuit assembled in 32 pins

shrunk dual in line plastic package. This IC controls all the functions

related to the horizontal and vertical deflection in multi modes or multi-

frequency computer display monitors.

The internal sync processor, combined with the very powerful geometry

correction block make the KB2512 suitable for very high performance

monitors with very few external components. The horizontal jitter level is

very low. It is particularly well suited for high-end 17” and 19” monitors.
