MSP 34x0G
Multistandard Sound Processor Family
General Description
The MSP 3410G 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 processed analog AF-out, is
performed on a single chip
This new generation of TV sound processing ICs now includes versions for processing the
multichannel television sound (MTS) signal conforming to the standard recommended by the
Broadcast Television Systems Committee (BTSC). The DBX noise reduction, or alternatively,
Micronas Noise Reduction (MNR) is performed.
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 3410G has optimum stereo performance without any adjustments. ,
The MSP 3410G has built-in automatic functions: The IC is able to detect the actual sound standard
automatically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can
be evaluated internally with subsequent switching between mono/ stereo/bilingual; no I2C interaction
is necessary (Automatic Sound Selection).
The MSP 3410G can handle very high FM deviations even in conjunction with NICAM processing.
This is especially important for the introduction of NICAM in China.
