MSP 34x0G
Multistandard Sound Processor Family
Release Note: Revision bars indicate significant
changes to the previous edition. The hardware and
software description in this document is valid for
the MSP 34x0G version C12 and following ver-
sions.
1. Introduction
The MSP 34x0G 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 34x0G.
These TV sound processing ICs now include versions
for processing the multichannel television sound
(MTS) signal conforming to the standard recom-
mended by the Broadcast Television Systems Com-
mittee (BTSC). The DBX noise reduction, or alterna-
tively, 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 34x0G has optimum stereo perfor-
mance without any adjustments.
All MSP 34xxG versions are pin compatible to the
MSP 34xxD. Only minor modifications are necessary
to adapt a MSP 34xxD controlling software to the
MSP 34xxG. The MSP 34x0G further simplifies con-
trolling software. Standard selection requires a single

The MSP 34x0G 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
matic Sound Selection).
The MSP 34x0G can handle very high FM deviations
even in conjunction with NICAM processing. This is
especially important for the introduction of NICAM in
China.
The ICs are produced in submicron CMOS technology.
The MSP 34x0G is available in the following pack-
ages: PSDIP64-1, PSDIP52-1/-2, PMQFP80-11, and
PMQFP64-2.
