The STV9422/24 is an ON SCREEN DISPLAY for monitor. It is built as a slave peripheral connected to a host MCU via a serial I2C bus. It includes a display memory, controls all the display attributes and generates pixels from the data read in its on chip memory. The line PLL and a special slice interpolator allow to have a display aspect which does not dependon theline and framefrequencies.
