The TDA9109/SN is a monolithic integrated circuit assembledin 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, combinedwith the very powerful geometry correction block make the TDA9109/SN suitable for very high performance monitors, using very few external components. The horizontaljitter level is very low. It is particularly well suited for high-end 15" and 17" monitors. Combined with the ST7275 Microcontroller family, TDA9206 (Video preamplifier) and STV942x (On-Screen Display controller) the TDA9109/SN allows fully I2 C bus controlled computer display monitors to be built with a reduced number of external components.
