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.
