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.

In addition, this encoder MSM7650 has an internal 9-bit DAC. So, when compared with using a conventional 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 of MSM7650 provided conforms to Philips's I2C 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.
