Video, Display, and Deflection Processor

Release Notes: This data sheet describes functions

and characteristics of the VDP 31xxB–C2. Revision

bars indicate significant changes to the previous

edition.

1. Introduction

The VDP 31xxB is a Video IC family of high-quality

single-chip video processors. Modular design and a

submicron technology allow the economic integration of

features in all classes of TV sets. The VDP 31xxB family

is based on functional blocks contained in the two chips:

VPC 3200A Video Processor and DDP 3300A Display

and Deflection Processor.

Each member of the family contains the entire video,

display, and deflection processing for 4:3 and 16:9

50/60 TV sets. Its performance and flexibility allow the

user to standardize his product development. Hardware

and software applications can profit from the modularity,

as well as manufacturing, systems support, or mainte-

nance. An overview of the VDP 31xxB video processor

family is shown in Fig. 1–1.
