DESCRIPTION
The TDA9109/SN 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, 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 fam-
ily, TDA9206 (Video preamplifier) and STV942x
(On-Screen Display controller) the TDA9109/SN
allows fully I
2
C bus controlled computer display
monitors to be built with a reduced number of
external components.
