MSM7650  
NTSC/PAL Digital Encoder  
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.  
Inaddition,thisencoderhasaninternal9-bitDAC.So,whencomparedwithusingaconventional  
analog encoder, the number of components, the board space, and points of adjustment can  
greatly be reduced, thereby realizing a low cost and high-accuracy system.

The host interface provided conforms to Philips's I C specifications, which reduces  
interconnections between this encoder and mounting components.  
The internal synchronization signal generator (SSG) allows the MSM7650 to operate in master  
or slave mode.
