MSP 34x5D

Multistandard Sound Processor

Release Notes: The hardware description in this

document is valid for the MSP 34x5D version A2 and

following versions. Revision bars indicate signifi-

cant changes to the previous edition.

1. Introduction

The MSP 34x5D is designed as a single-chip Multistan-

dard Sound Processor for applications in analog and

digital TV sets, video recorders, and PC-cards. As deriv-

ative versions of the MSP 34x0D, the MSP 34x5D com-

bines all demodulator features of the MSP 34x0D with

less I/O and reduced audio baseband processing.

The IC is produced in submicron CMOS technology,

combined with high-performance digital signal proces-

sing. The MSP 34x5D is available in the following

packages: PLCC68, PSDIP64, PSDIP52, PQFP80, and

PMQFP44.

Note: The MSP 34x5D version has reduced control reg-

isters and less functional pins. The remaining registers

are software compatible to the MSP 3410D. The pinning

is compatible to the MSP 3410D.
