4-2 MSP341x Multistandard Sound Processor

The MSP 341x is designed as a single-chip Multistandard Sound Processor for applications in analogue and digital TV sets, video recorders, and PC cards.

The MSP3411 has all functions of MSP3410 with the addition of a virtual surround sound feature. A Surround sound affect can be rproduced with two loudspeakers. The MSP3411 includes virtualizer

algorithm “3D Panorama” which has been approved by the Dolby laboratories for compliance with the “Virtual Dolby Surround” technology. In addition, the MSP3411 includes Micronas “Panorama” algorithm.

MSP 341x features :

-sound IF input

-No external filters required

-Stereo baseband input via integrated AD converters

-Two pairs of DA converters

-Two carrier FM or NICAM processing

-AVC : Automatic Volume Correction

-Bass, treble, volume processing

-Full SCART in/out matrix without restrictions

-Improved FM-identification

-Demodulator short programming

-Autodetection for terrestrial TV - sound standards

-Precise bit-error rate indication

-Automatic switching from NICAM to FM/AM or vice versa

-Improved NICAM synchronisation algorithm

-Improved carrier mute algorithm

-Improved AM-demodulation

-Reduction of necessary controlling

-Less external components

4-2-1- Basic Features of the MSP 341x

4-2-1-1 Demodulator and NICAM Decoder Section

The MSP 341x is designed to simultaneously perform digital demodulation and decoding of NICAM-coded TV stereo sound, as well as demodulation of FM or AM mono TV sound. Alternatively, two carrier FM systems according to the German terrestrial specs can be processed with the MSP 341x.

The MSP 341x facilitates profitable multistandard capability, offering the following advantages:

-Automatic Gain Control (AGC) for analogue input: input range: 0.10 - 3 Vpp

-integrated A/D converter for sound-IF input

-all demodulation and filtering is performed on chip and is individually programmable

-easy realisation of all digital NICAM standards (B/G, I, L and D/K)

-FM-demodulation of all terrestrial standards (include identification decoding)

-no external filter hardware is required

-only one crystal clock (18.432 MHz) is necessary
