Product Summary
The S5D2509X09-S0T0 is a stand-alone OSD Processor, which is used to display monitor adjustment or status information as a certain character or symbol on screen. Its basic operation includes making the R/ G/ B signal for the character or symbol by controlling the internal memory, synchronizing it with the horizontal flyback signal, and mixing it with the main video signal in the video AMP IC. The font data for making the character or symbol is stored in the internal ROM. The S5D2509X09-S0T0 is accessed and controlled by the control data, transmitted from the micro controller through the I2C bus. The S5D2509X09-S0T0 contains internal PLL circuitry, so all timing control signals, including the system clock, are synchronized with the horizontal flyback signal.
