PRELIMINARY DATA SHEET
2. Features of the MSP 3400C
2.1. Features of the Demodulator and Decoder
Sections
The MSP 3400C is designed to perform demodulation
of FM-mono TV sound and two carrier FM systems ac-
cording to the German or Korean terrestrial specs. With
certain constraints, it is also possible to do AM-demodu-
lation according to the SECAM system. Alternatively, the
satellite specs can be processed with the MSP 3400C.
For FM carrier detection in satellite operation, 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 to-
wards multistandard capability with its very flexible
application and may be used in TV-sets, satellite tuners,
and video recorders.
The MSP 3400C 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
– no external filter hardware is required
– only one crystal clock (18.432 MHz) is necessary
– FM carrier level calculation for automatic search algo-
rithms and carrier mute function
– high deviation FM-mono mode (max. deviation:
approx. $360 kHz)
2.2. Features of the DSP-Section
– flexible selection of audio sources to be processed
– digital input and output interfaces via I2S-Bus for exter-
nal DSP-processors, surround sound, ADR etc.
– digital interface to process ADR (Astra Digital Radio)
together with DRP 3510 A
– performance of all deemphasis systems including
adaptive Wegener Panda 1 without external compo-
nents or controlling
– digitally performed FM-identification decoding and de-
matrixing
– digital baseband processing: volume, bass, treble,
5-band equalizer, loudness, pseudostereo, and base-
width enlargement
– simple controlling of volume, bass, treble, equalizer
etc.
– increased audio bandwidth for FM-Audio-signals
(20 Hz – 15 kHz, $1 dB)
2.3. Features of the Analog Section
– three selectable analog pairs of audio baseband in-
puts (= three SCART inputs)
input level: 2 V RMS,
input impedance: 25 k
– one selectable analog mono input (i.e. AM sound),
input level: 2 V RMS,
input impedance: 10 k
– two high quality A/D converters, S/N-Ratio: 85 dB
– 20 Hz to 20 kHz Bandwidth for SCART-to-SCART-
Copy facilities
– MAIN (loudspeaker) and AUX (headphones): two
pairs of 4-fold oversampled D/A-converters
output level per channel: max. 1.4 V RMS
output resistance: max. 5 k
S/N-Ratio: 85 dB at maximum volume
max. noise voltage in mute mode: 10 µV (BW: 20 Hz
...16 kHz)
– one pair of four-fold oversampled D/A-converters sup-
plying two selectable pairs of SCART-Outputs. Output
level per channel: max. 2 V RMS, output resistance:
max. 0.5 k, S/N-Ratio: 85 dB
(20 Hz...16 kHz)
