MSP 34x1G
Multistandard Sound Processor Family with Virtual
Dolby Surround
The hardware and software description in this doc-
ument is valid for the MSP 34x1G version A1 and
following versions.
1. Introduction
The MSP 34x1G family of single-chip Multistandard
Sound Processors covers the sound processing of all
analog TV-Standards worldwide, as well as the NICAM
digital sound standards. The full TV sound processing,
starting with analog sound IF signal-in, down to pro-
cessed analog AF-out, is performed on a single chip.
Figure 1–1 shows a simplified functional block diagram
of the MSP 34x1G.
The MSP 34x1G has all functions of the MSP 34x0G
with the addition of a virtual surround sound feature.
Surround sound can be reproduced to a certain extent
with two loudspeakers. The MSP 34x1G includes our
virtualizer algorithm “3D-PANORAMA” which has been
approved by the Dolby
with the "Virtual Dolby Surround" technology. In addi-
tion, the MSP 34x1G includes our “PANORAMA” algo-
rithm.
These TV sound processing ICs include versions for
processing the multichannel television sound (MTS)

the Broadcast Television Systems Committee (BTSC).
The DBX noise reduction, or alternatively, MICRONAS
Noise Reduction (MNR) is performed alignment free.
Other processed standards are the Japanese FM-FM
multiplex standard (EIA-J) and the FM Stereo Radio
standard.
Current ICs have to perform adjustment procedures in
order to achieve good stereo separation for BTSC and
EIA-J. The MSP 34x1G has optimum stereo perfor-
mance without any adjustments.
All MSP 34x1G versions are pin and software down-
ward-compatible to the MSP 34x0D. The MSP 34x1G
further simplifies controlling software. Standard selec-
tion requires a single I
The MSP 34x1G has built-in automatic functions: The
IC is able to detect the actual sound standard automat-
ically (Automatic Standard Detection). Furthermore,
pilot levels and identification signals can be evaluated
internally with subsequent switching between mono/
stereo/bilingual; no I

The ICs are produced in submicron CMOS technology.
The MSP 34x1G is available in the following pack-
ages: PLCC68, PSDIP64, PSDIP52, PQFP80, and
PLQFP64.
