W9971CF - Video Graphics Controller With TV Encoder

General Description

Winbond s W9971CF is a highly-integrated VLSI providing high performance graphics acceleration and TV-quality full screen motion video acceleration for IBM PCs or compatibles.

The W9971CF integrates an NTSC/PAL TV encoder with S-Video or composite video for flicker-free and glueless TV output.

Key Features

  • high-quality video filtering, bilinear interpolating scaling along both the X and Y axes, color space conversion and overlay keying. In addition to accelerating software video playback, the W9971CF also provides an advanced multimedia video interface for glueless interfacing to major TV decoders such as the Philips SAA711X and the Brooktree Bt815A/7A/9A. The 16-bit baseline VESA Advanced Feature Connector (VAFC) and the 8-bit bidirectional IBM Feature Connector are also supported for legacy vide.
