2000 DATA SHEET S5D2501F OSD PROCESSOR FOR MONITORS S5D2501F OVERVIEW The S5D2501F is used to display some characters or symbols on a screen of monitor.

Basically, the operation is to control the internal memory on chip and generate the R,G,B signals for some characters or symbols.

The R,G,B signals are synchronized with the horizontal sync.

Then the R,G,B signals are mixed with the main video signal in the Video Amp IC.

The font data for characters or symbols are stored in the internal
