STV6889 General Description


The STV6889 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.

Combined with other ST components dedicated for CRT monitors (microcontroller, video preamplifier,video amplifier, OSD controller), the STV6889 allows fully I2C bus-controlled computer display monitors to be built with a reduced number of external components.
