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.
