DESCRIPTION
The STV6886 is a monolithic integrated circuit assembled 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
STV6886 suitable for very high performance monitors, using few external components.
Combined with other ST components dedicated
for CRT monitors (microcontroller, video preamplifier, video amplifier, OSD controller) the STV6886
allows fully I2C bus-controlled computer display
monitors to be built with a reduced number of external components.
