The TDA9109A is a monolithic integrated circuit assembled in a 32-pin shrink dual in line plastic package. 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 TDA9109A suitable for very high performance monitors, using very 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 TDA9109A allows fully I2C bus-controlled computer display monitors to be built with a reduced number of external components .
