DESCRIPTION

The TDA9111 is a monolithic integrated circuit as-

sembled in a 32-pin shrink dual-in-line plastic

package. This IC controls all the functions related

to horizontal and vertical deflection in multimode

or multi-frequency computer display monitors.

The internal sync processor, combined with the

powerful geometry correction block, makes the

TDA9111 suitable for very high performance mon-

itors, using few external components.

The horizontal jitter level is very low. It is particu-

larly well-suited to high-end 15” and 17” monitors.

Combined with the ST7275 Microcontroller family,

TDA9206 (Video preamplifier) and STV942x (On-

Screen Display controller), the TDA9111 allows

fully-I2C bus-controlled computer display monitors

to be built with a reduced number of external com-

ponents.
