MSM7653 Datasheet | OKI Electric

DESCRIPTION The MSM7653 is a digital NTSC/PAL encoder. By inputting digital image data conforming to ITU Rec. 656 or ITURBT 601, it outputs selected analog posite video signals, analog S video signals. For the scanning system, interlaced or noninterlaced mode can be selected. Since the MSM7653 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 pared with using a conventional analog encoder, the number of ponents, the board space, and points of adjustment can greatly be reduced, thereby realizing a low cost and high-accuracy system. The MSM7653 provides the optional functions such as Macrovision Rev. 7.01 (note 1) (note 2) and Closed Caption Signal Generation Function. The host interface provided conforms to Philips's I2C specifications, which reduces interconnections between this encoder and mounting ponents. The internal synchronization signal generator (SSG) allows the MSM7653 to operate in master mode.
