OSD PRESSOR FOR MONITOR (PRELIMINARY)
S5D2509
PRODUCT SUMMARY
INTRODUCTION
S5D2509 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. It is accessed and controlled by the control data, transmitted from the micro controller through the
I
2
C bus. The chip contains internal PLL circuitry, so all timing control signals, including the system clock, are
synchronized with the horizontal flyback signal.
