PRELIMINARY DATA SHEET
VDP 31xxB
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.

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:
