PRELIMINARY DATA SHEET
MSP 34x5D
– Bass, treble, volume, loudness, and spatial effects
processing
– Full SCART in/out matrix without restrictions
– Improved FM-identification (as in MSPC)
– Demodulator short programming
– Autodetection for terrestrial TV-sound standards
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.
– Improved carrier mute algorithm (as in MSPD)
– Improved AM-demodulation (as in MSPD)
– Digital control output pins D_CTR_OUT0/1
– Reduction of necessary controlling
– Less external components
1.2. Specific MSP 3415D Features
– All NICAM standards
– Precise bit-error rate indication
– Automatic switching from NICAM to FM/AM or vice
versa
– Improved NICAM synchronization algorithm
1.3. Unsupported MSP 34x0D Functions
– Equalizer
1.1. Common Features of MSP 34x5D
– Dolby Pro Logic together with DPL 351xA
– Analog sound IF input
– No external filters required
– Stereo baseband input via integrated A/D converters
– Two pairs of D/A converters
– Two carrier FM
– I

S Interface for version B3 and later versions
– AVC: Automatic Volume Correction
1.4. MSP 34x0D Inputs and Outputs not included in
the MSP 34x5D
– 2nd IF input
– 3rd and 4th SCART input
– 2nd SCART output
– 2nd SCART DA
– Headphone output
– Subwoofer output
– ADR interface
