GENERAL DESCRIPTION

The MSM7650 is a digital NTSC/PAL encoder. By inputting digital image data conforming to CCIR Rep624-4, it outputs analog composite video signals and analog S video signals. For the scanning system, interlaced or noninterlaced mode can be selected.

Since the MSM7650 is provided with pins dedicated to overlay function, text and graphics can be superimposed on a video signal.
