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.
