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.
In addition, this encoder has an internal 10-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 MSM7652 provides the optional functions such as Closed Caption Signal Generation Function.
The host interface provided conforms to Philips's I²C specifications, which reduces interconnections between this encoder and mounting components.
The internal synchronization signal generator (SSG) allows the MSM7652 to operate in master mode.
