DESCRIPTION
The TDA9109A is a monolithic integrated circuit
assembled in a 32-pin shrink dual in line plastic
package. This IC controls all the functions related
to the horizontal and vertical deflection in multi-
mode or multi-frequency computer display moni-
tors.
The internal sync processor, combined with the
very powerful geometry correction block, make
the TDA9109A suitable for very high performance
monitors, using very few external components.
The horizontal jitter level is very low. It is particu-
larly well-suited to high-end 15” and 17” monitors.
Combined with the ST7275 Microcontroller family,
TDA9206 (Video preamplifier) and STV942x (On-
Screen Display controller), the TDA9109A allows
fully I2C bus-controlled computer display monitors
to be built with a reduced number of external com-
ponents
.
