DESCRIPTION
The STV9118 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
STV9118 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 STV9118
allows fully I
2
C bus-controlled computer display
monitors to be built with a reduced number of ex-
ternal components.
