MSM7652

NTSC/PAL Digital Video Encoder

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.

Since the MSM7652 is provided with pins dedicated to overlay function, text and graphics can

be superimposed on a video signal.

Inaddition,thisencoderhasaninternal10-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 MSM7652 provides the optional functions such as Closed Caption Signal Generation

Function.

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 MSM7652 to operate in master

mode.
