The VCT 48/49xyI is an IC family of high-quality single-chip TV processors. Modular design and deep-submicron technology allow the economic integration of features in all classes of single-scan CRT TV sets and FPD TV sets. 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 and Closed-Caption acquisition. The VCT 48/49xyI family offers a rich feature set, covering the whole range of state-of-the-art 50/60 Hz CRT and FPD TV applications. |
