13.3.MSP34X0G (MSP3410G)
13.3.1.Description
The MSP 34x0G family of single-chip Multi standard 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. Figure shows a simplified functional block diagram of the MSP 34x0G.
evaluated internally with subsequent switching between mono/stereo/bilingual; no I

C interaction is
necessary (Automatic Sound Selection).
This new generation of TV sound processing ICs now includes versions for processing the multi
channel 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 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 performance without any adjustments.
All MSP 34x0G versions are pin and software downward compatible to the MSP34x0D. The
MSP34x0G further simplifies controlling software. Standard selection requires a single I

only.
The MSP 34x0G 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
