Introduction

The VCT 38xxA is an IC family of high-quality singlechip TV processors. Modular design and a submicron technology allow the economic integration of features in all classes of TV sets. The VCT 38xxA family is based on functional blocks contained and approved in existing products like VDP 3120B, TPU 3050S, and CCZ 3005K.
