MSP 3400C

Multistandard Sound Processor

Release Notes: The hardware description in this

document is valid for the MSP 3400C – C8 and newer

codes. Revision bars indicate significant changes

to the previous version.

1. Introduction

The MSP 3400C is designed as single-chip Multistan-

dard Sound Processor for applications in analog and

digital TV sets, satellite receivers and video recorders.

The MSP-family, which is based on the MSP 2400, dem-

onstrates the progressive development towards highly

integrated multi-functional ICs.

The MSP 3400C, again, improves function integration:

The full TV sound processing, starting with analog

sound IF signal-in, down to processed analog AF-out, is

performed in a single chip. The IC is produced in 0.8 µm

CMOS technology, combined with high performance

digital signal processing.

The MSP 3400C 0.8 µ CMOS version is fully pin and

software compatible to the 1.0 µ MSP 3400 and MSP

3410. The main difference between the MSP 3400C and

the MSP 3410, consists of the MSP 3410 being able to

decode NICAM signals.

The MSP 3400C is available in PLCC68, PSDIP64,

PSDIP52, and PQFP80 package.

Note: To achieve compatibility with the functions of MSP

3400 and MSP 3410 (except NICAM), the load se-

quences must be programmed as described in the data

sheet of MSP 3410.

MSP 3400C Integrated Functions:

– FM-demodulation of all terrestrial standards (incl. identification decoding)

– FM-demodulation of all satellite standards

– various deemphasis types (incl. Panda1)

– volume, balance, bass, treble, loudness for loudspeaker and headphone output

– automatic volume correction (A.V.C.)

– 5 band graphic equalizer

– subwoofer output alternatively with headphone output

– spatial effect (pseudostereo/basewidth enlargement)

– ADR together with DRP 3510 A

– Dolby ProLogic together with DPL 3418/19/20 A

– 3 pairs of D/A converters

– 1 pair of A/D converters

– SCART switches
