Multistandard Sound Processors

Release Notes: The hardware description in this

document is valid for the MSP 34x0D version B3

and following versions. Revision bars indicate sig-

nificant changes to the previous edition.

1. Introduction

The MSP 34x0D is designed as a single-chip Multi-

standard Sound Processor for applications in analog

and digital TV sets, satellite receivers, video recorders,

and PC cards.

The MSP 34x0D, 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. It covers all European

TV standards (some examples are shown in Table 3–1).

The MSP 3400D is fully pin and software-compatible

to the MSP 3410D, but is not able to decode NICAM. It

is also compatible to the MSP 3400C.

The IC is produced in submicron CMOS technology,

combined with high-performance digital signal pro-

cessing. The MSP 34x0D is available in the following

packages: PLCC68, PSDIP64, PSDIP52, PQFP80,

and PLQFP64.

Note: The MSP 3410D version is fully downward-com-

patible to the MSP 3410B, the MSP 3400B, and the

MSP 3400C. To achieve full software-compatibility with

these types, the demodulator part must be programmed

as described in the data sheet of the MSP 3410B.
