DEFLECTION PROCESSOR FOR MULTISYNC MONITORS

KB2511B

DEFLECTION PROCESSOR

The KB2511B is a monolithc integrated circuit assem-

bled 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 com-

puter 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.
