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鈥?and 17鈥?/div>
monitors.
