DEFLECTION PROCESSOR FOR MULTISYNC MONITORS KB2511B

DEFLECTION PROCESSOR

The KB2511B is a monolithc 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 multimodes or multi-frequency computer display monitors. The internal sync processor, combined with the very powerful geometry correction block make the KB2511 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 15” and 17” monitors.
