MSP 34XXG
General description:
The MSP 34xxG 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 so und IF signal-in, down to processed analog
AF-out, is performed on a single chip.
Two-carrier FM systems according to the German or Korean terrestrial specs or the satellite specs
can be processed with the MSP 34x0G. Digital demodulation and decoding of N ICAM-coded TV
stereo sound, is done only by the MSP 3410G. The MSP 34x0G offers a powerful feature to
calculate the carrier field strength, which can be used for automatic standard detection (terrestrial)
and search algorithms (satellite).
The MSP 3411G has all functions of the MSP34x0G with the addition of a virtual surround sound
feature. Surround sound can be reproduced to a certain extent with two loudspeakers. The
MSP3411G includes our virtualizer algorithm ?3D-PANORAMA? which has been approved by the
Dolby Laboratories for compliance with the "Virtual Dolby Surround" technology. In addition, the
MSP 34x1G includes our ?PANORAMA? algorithm. The MSP34x1G has built-in automatic
functions: The IC is able to detect the actual sound standard automatically (A utomatic Standard
