General Description
Release Note: This data sheet describes functions
and characteristics of the VCT 49xyI, VCT 48xyI
version F1.
1. Introduction
The VCT 49xyI, VCT 48xyI is an IC family of high-qual-
ity single-chip TV processors. Modular design and
deep-submicron technology allow the economic inte-
gration of features in all classes of single-scan TV
sets. The VCT 49xyI, VCT 48xyI 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 inte-
grated microcontroller is supported by a powerful OSD
generator with integrated Teletext & CC acquisition
including on-chip page memory.
