PRELIMINARY DATA SHEET
VDP 31xxB
Video, Display, and Deflection Processor
VPC 3200A Video Processor and DDP 3300A 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.
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.
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:
