DESCRIPTION

The TDA9109/S is a monolithic integrated circuit

assembled in 32-pin shrink dual in line plastic pack-

age. This IC controls all the functions related to the

horizontal and vertical deflection in multimode or

multi-frequency computer display monitors.

The internal sync processor, combined with the very

powerful geometry correction block make the

TDA9109/S suitable for very high performance

monitors, using very few external components.

The horizontal jitter level is very low. It is particularly

well suited for high-end 15" and 17" monitors.

Combined with the ST7275 Microcontroller fam-

ily, TDA9206 (Video preamplifier) and STV942x

(On-Screen Display controller) the TDA9109/S

allows fully I

monitors to be built with a reduced number of

external components.
