The VCT 6wxyP family is dedicated to high-quality FPD and double-scan TV sets. The IC enables an economic single-package FPD TV solution without any external devices. Even memory and program ROM are integrated in the IC. The pin-compatible VCT 6wxyP family represents a unique concept offering a scaleable feature set. This allows the design of a complete range of TV sets based on a common and economic hardware and software platform.

Modular design and deep submicron technology allow the integration of audio, video, teletext, OSD, and controller-related functionalities. They cover the whole range of flat-panel display TVs and all classes of double-scan CRT TV sets. The IC is based on proven functional blocks of existing products like VCT 49xxI, VSP 94x5B, and DPS 94xxB.

Each member of the IC family contains the entire audio, video, upconversion processing for 4:3 and 16:9 50/60 Hz progressive or 100/120 Hz interlaced stereo TV sets plus the control/data interface for flat-panel displays. The integrated microcontroller is supported by a powerful OSD and graphics generator with integrated teletext acquisition.

System Architecture

Post-scaling in the display processing block ensures the desired output format. Display processing is supported by an 8-bit 8051-compatible controller. By means of powerful alpha-blending, the graphics mixer composes the output image from following image layers: the video layer, the OSD layer and the pixel graphics layer.

The audio part consists of a multistandard sound IF demodulator and a baseband processor supporting all desired sound features in this range.

A connection for additional features, such as advanced motion compensation via -Micronas’ FRC 94xyA, is also provided.
