The MSP 3410 B is a single-chip Multistandard Sound Processor for applications in analog and digital TV sets, satellite receivers and video recorders.
The MSP-family, which goes back to the MSP 2400, demonstrates in an impressive way the progressive de-velopment towards highly integrated ICs, offering more and more features and flexibility. The development of the MSP 2410 included an automatic gain control but re-duced the amount of external components. The MSP 2410 reached a high level of performance and is the ba-sis for the new generation.
The MSP 3410 B increases function integration in a spectacular way. By including the MSP2410 as a library cell and combining it with AD/DA converters and high performance digital signal processing, the chip offers a wide range of features. The complete TV-sound-proces-sing, starting at the Sound-IF domain, will be performed by one single IC. The inputs of the IC are analog audio signals in baseband and at intercarrier position. The MSP 3410 B covers the sound processing of a wide range of TV-standards. Some examples are listed in Table 31.
The MSP 3410 B is produced in 1.0 m CMOS technolo-gy and is available in 68-pin PLCC and in 64-pin PSDIP packages.

1) positive value means current flowing into the circuit
2) "n" means "1" or "2", "s" means "L" or "R"
3) The Analog Outputs are short-circuit proof with respect to First Supply Voltage and Ground.
4) Total chip power dissipation must not exceed absolute maximum rating.
Stresses beyond those listed in the "Absolute Maximum Ratings" may cause permanent damage to the device. This
is a stress rating only. Functional operation of the device at these or any other conditions beyond those indicated in the "Recommended Operating Conditions/Characteristics" of this specification is not implied. Exposure to absolute maxi-mum ratings conditions for extended periods may affect device reliability.
` Features of the Demodulator and Decoder Sections
The MSP 3410 B is designed to simultaneously perform digital demodulation and decoding of NICAM-coded TV stereo sound, as well as demodulation of FM-mono TV sound. Alternatively, two carrier FM systems according to the German or Korean terrestrial specs or the satellite specs can be processed with the MSP 3410 B.
Since it is simple and economic to demodulate AM sound carriers with conventional sound-IF-mixing units, the AM demodulation feature of the MSP will seldom be used. However, for FM carrier detection in satellite oper-ation the AM demodulation offers a powerful feature to calculate the carrier field strength, which can be used for automatic search algorithms. So the IC facilitates a first step towards multistandard capability with its very flex-ible application and may be used in TV-sets, satellite tuners and video recorders.
The MSP 3410 B facilitates profitable multistandard ca-pability, offering the following advantages:
two selectable analog inputs (TV- and SAT-IF sources)
Automatic Gain Control (AGC) for analog input: input range: 0.14 3 Vpp
integrated A/D converter for sound-IF inputs
all demodulation and filtering is performed on chip and is individually programmable
simple realization of both digital NICAM standards (UK/Scandinavia)
no external filter hardware is required
only one crystal clock (18.432 MHz) is necessary
Pay-TV for NICAM-mode
FM carrier level calculation for automatic search algo-rithms and carrier mute function
high deviation FM-mono mode (max. deviation: approx. ±360 kHz)
` Features of the DSP-Section
flexible selection of audio sources to be processed
digital input and output interfaces via S-Bus for DMA-2 via AMU, and via I S-Bus for external DSP-Proces-sors featuring Graphic Equalizer, Surround Sound etc.
performance of all deemphasis systems including adaptive Wegener Panda 1 without external compo-
nents or controlling
performance of D2MAC audio together with an AMU 2481
digitally performed FM-identification decoding and de-matrixing
digital baseband processing: volume, bass, treble,pseudostereo and basewidth enlargement
simplified controlling of volume, bass, treble etc.
increased audio bandwidth for FM-Audio-signals (20 Hz 15 kHz , ±1 dB)
` Features of the Analog Section
