1.1. Common Features of MSP 34x0D
– AVC: Automatic Volume Correction
– Subwoofer Output
– 5-band graphic equalizer (as in MSP 3400C)
– Enhanced spatial effect (pseudostereo/basewidth
enlargement as in MSP 3400C)
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.
– headphone channel with balance, bass, treble, loud-
ness
– balance for loudspeaker and headphone channels
in dB units (optional)
– D/A converters for SCART2 out
– improved oversampling filters (as in MSP 3400C)
– Four SCART inputs
– Full SCART in/out matrix without restrictions
– SCART volume in dB units (optional)
– Additional I
2
S input (as in MSP 3400C)
– New FM identification (as in MSP 3400C)
– Demodulator short programming
– Autodetection for terrestrial TV sound standards
– Improved carrier mute algorithm
– Improved AM demodulation
– ADR together with DRP 3510A
– Dolby Pro Logic together with DPL 351xA
– Reduction of necessary controlling
– Less external components
– Significant reduction of radiation
1.2. Specific Features of MSP 3410D
– All NICAM standards
– Precise bit-error rate indication
– Automatic switching from NICAM to FM/AM or vice-
versa
– Improved NICAM synchronization algorithm
