PRELIMINARY DATA SHEET

2. Basic Features of the MSP 34x5D

2.1. Demodulator and NICAM Decoder Section

The MSP 3415D 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 pro-

cessed with the MSP 34x5D.

The MSP 34x5D facilitates profitable multistandard ca-

pability, offering the following advantages:

– Automatic Gain Control (AGC) for analog 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 realization of all digital NICAM standards

(B/G, I, L and D/K, not for MSP 3405D)

– FM-demodulation of all terrestrial standards

(including identification decoding)

– no external filter hardware is required

– only one crystal clock (18.432 MHz) is necessary

– high deviation FM-mono mode

(max. deviation: approx. ±360 kHz)

2.2. DSP-Section (Audio Baseband Processing)

– two digital inputs and one digital output via I2S bus for

external signal processors like the DPL 351x.

– flexible selection of audio sources to be processed

– performance of terrestrial deemphasis systems

(FM, NICAM)

– digitally performed FM-identification decoding and

dematrixing

– digital baseband processing: volume, bass, treble,

loudness, and spatial effects

– simple controlling of volume, bass, treble, loudness,

and spatial effects

2.3. Analog Section

– two selectable analog pairs of audio baseband inputs

(= two SCART inputs)

input level: ≤2 V RMS,

input impedance: ≥25 kΩ

– one selectable analog mono input (i.e. AM sound):

input level: ≤2 V RMS,

input impedance: ≥15 kΩ

– two high-quality A/D converters, S/N-Ratio: ≥85 dB

– 20 Hz to 20 kHz bandwidth for

SCART-to-SCART-copy facilities

– loudspeaker: one pair of four-fold oversampled

D/A-converters

output level per channel: max. 1.4 VRMS

output resistance: max. 5 kΩ

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

supplying a pair of SCART-outputs.

output level per channel: max. 2 V RMS,

output resistance: max. 0.5 kΩ,

S/N-Ratio: ≥85 dB (20 Hz...16 kHz)
