PRELIMINARY DATA SHEET

Multistandard Sound Processor Family with Dolby

Surround Pro Logic

Release Note: Revision bars indicate significant

changes to the previous edition. The hardware and

software description in this document is valid for

the MSP 34x2G version A2 and following versions.

1. Introduction

The MSP 34x2G family of single-chip Multistandard

Sound Processors covers the sound processing of all

analog TV-Standards worldwide, as well as the NICAM

digital sound standards. The full TV sound processing,

starting with analog sound IF signal-in, down to pro-

cessed analog AF-out, is performed on a single chip.

The family’s latest member, the MSP 34x2G has all

functions of the MSP 34x0G with the addition of Dolby

Surround Pro Logic and Virtual Dolby Surround sound

processing (See License Notice on page 5). The

MSP 34x2G forms a superset of the functions of the

MSP 34x1G, which contains the virtualizer algorithms

but does not contain any multi-channel processing.

Additional output pins DACM_C and DACM_S have

been defined which deliver the Dolby Surround Pro

Logic processed Center and Surround channels.

When DACM_C and DACM_S are active, the head-

phone outputs DACA_L and DACA_R are muted and

vice versa. Simultaneous processing of Headphone

signals and Dolby Surround Pro Logic is not possible.

Surround sound can be reproduced to a certain extent

with only two loudspeakers. The MSP 34x2G includes

a Micronas virtualizer algorithm which has been

approved by the Dolby1) Laboratories for compliance

with the "Virtual Dolby Surround" technology. This

algorithm is called “3D-PANORAMA” and enables con-

vincing acoustical sensations. Virtual Dolby Surround

can be processed together with headphone signals.

The ICs are produced in submicron CMOS technology.

The MSP 34x2G is available in the following packages:

PQFP80, PLQFP64, and PSDIP64.
