7.1)VCT 49XYI
GENERAL DECRIPTION
The VCT 49xyI is an IC family of high-quality singlechip TV processors. Modular design and deep-
submicron technology allow the economic integration of features in all classes of single-scan TV sets.
The VCT 49xyI family is based on functional blocks contained and approved in existing products like
DRX 396xA, MSP 34x5G, VSP 94x7B, DDP 3315C, and SDA 55xx.
Each member of the family contains the entire IF, audio, video, display, and deflection processing for
4:3 and 16:9 50/60-Hz mono and stereo TV sets. The integrated microcontroller is supported by a
powerful OSD generator with integrated Teletext & CC acquisition including on-chip page memory.
