DESCRIPTION
The TDA9109/N is a monolithic integrated circuit
assembledin 32-pin shrink dual in line plastic pack-
age. 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
TDA9109/N 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/N allows
fully I2C bus controlled computer display monitors
to be built with a reduced number of external
comp onen ts.
