The TDA9111 is a monolithic integrated circuit assembled 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 monitors, using few external components.
The horizontal jitter level is very low. It is particularly well-suited to high-end 15” and 17” monitors.
Combined with the ST7275 Microcontroller family,
TDA9206 (Video preamplifier) and STV942x (OnScreen Display controller), the TDA9111 allows
fully-I2C bus-controlled computer display monitors
to be built witha reduced number of external components.
