DESCRIPTION
The TDA9110 is a monolithic integrated circuit as-
sembled in 32-pin shrunk 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 synchro processor, combined with the
very powerful geometry correction block make the
TDA9110 suitable for very high performance moni-
tors with very few external components.
The horizontal jitter level is extremely low. (Typical
standard deviation : 300ps @ 31kHz).
It is particularly well suited for high-end 15” and 17”
monitors.
PRODUCT PREVIEW
Combined with ST7275 Microcontroller family,
TDA9206 (Video preamplifier) and STV942x
(On-Screen Display controller) the TDA9110
allows to built fully I²C bus controlled computer
display monitors, with a reduce nu mber of ex-
ternal compon ents.
