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.

Combined with ST7275 Microcontroller family,

TDA9206 (Video preamplifier) and STV942x

(On-Screen Display controller)

the TDA9110

allows to built fully I

display monitors, with a reduce nu mber of ex-

ternal compon ents.
