VCT 38xxA/B
Video/Controller/Teletext IC Family
Release Note: This data sheet describes functions
and characteristics of the VCT 38xxA-C4 and
VCT 38xxB-D6.
1. Introduction
The VCT 38xxA/B is an IC family of high-quality single-
chip TV processors. Modular design and a submicron
technology allow the economic integration of features
in all classes of TV sets. The VCT 38xxA/B family is
based on functional blocks contained and approved in
existing products like VDP 3120B, TPU 3050S, and
CCZ 3005K.
Each member of the family contains the entire video,
display, and deflection processing for 4:3 and 16:9 50/
60-Hz TV sets. The integrated microcontroller is sup-
ported by a powerful OSD generator with integrated
teletext acquisition which can be upgraded with on-
chip page memory. With volume control and audio
input select the basic audio features for mono TV sets
are integrated. An overview of the VCT 38xxA/B sin-
gle-chip TV processor family is given in Fig. 1–1 on
page 7.
The VCT 38xxA/B family offers a rich feature set, cov-
ering the whole range of state-of-the-art 50/60-Hz TV
applications.
In comparison to the VCT 38xxA the VCT 38xxB offers
the following features:
– one additional composite video input
– analog luma/chroma adder for video output
– closed caption module
– additional 12k character ROM
