GENERAL DESCRIPTION

The MSM7652 is a digital NTSC/PAL encoder. By inputting digital image data conforming to ITU Rec. 656 or ITURBT 601, it outputs selected analog composite video signals, analog S video signals or Y, R-Y, B-Y signals. For the scanning system, interlaced or noninterlaced mode can be selected.
