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.
