DESCRIPTION
The TDA9113 is a monolithic integrated circuit as-
sembled in a 32-pin shrink dual-in-line plastic
package. This IC controls all the functions related
to horizontal and vertical deflection in multimode
or multi-frequency computer display monitors.
The internal sync processor, combined with the
powerful geometry correction block, makes the
TDA9113 suitable for very high performance mon-
itors, using few external components.
Combined with other ST components dedicated
for CRT monitors (microcontroller, video preampli-
fier, video amplifier, OSD controller) the TDA9113
allows fully I
monitors to be built with a reduced number of ex-
ternal components.
FOR MULTISYNC MONITOR
Generates waveforms for dynamic corrections
1 output with vertical dynamic correction
1 output with horizontal dynamic correction
Fixed on screen by means of tracking system
