MSP 44x8G
the reception of digital stereo signals with arbitrary
sample rates from 5 to 50 kHz. Synchronization is per-
formed by means of a high-quality adaptive sample
rate converter. All I
2
S input signals are upsampled to
48 kHz.
The MSP 44x8G offers the following automatic func-
tions:
– ASD (Automatic Standard Detection) detects the
actual broadcasted TV standard automatically.
– ASS (Automatic Sound Select) switches automati-
cally (without any I2C action) between mono/stereo/
bilingual when the broadcast mode changes.
This generation of TV sound processing ICs includes
versions for processing the multichannel television
sound (MTS) signal conforming to the U.S. standard
recommended by the Broadcast Television Systems
Committee (BTSC). The DBX noise reduction, or alter-
natively, Micronas Noise Reduction (MNR) is per-
formed alignment free. Apart from all 2-carrier stan-
dards, other processed standards are the Japanese
FM-FM multiplex standard (EIA-J) and the FM Stereo
Radio standard.
The MSP 44x8G versions are pin and software com-
patible to other MSP families. Standard selection
requires only a single I
2
C transmission.
The ICs are produced in submicron CMOS technology
and are available in the following packages:
PMQFP80-11, PMQFP64-2, and PSDIP64-1.
Multistandard Sound Processor Family
Release Note: Revision bars indicate significant
changes to the previous edition. The hardware and
software description in this document is valid for
the MSP 44x8G version B3 and following versions.
1. Introduction
The MSP 44x8G family of Multistandard Sound Pro-
cessors cover the demodulation and stereo decoding
of all analog TV-Standards worldwide, as well as the
NICAM digital sound standards and FM stereo radio.
The full demodulation and decoding, starting with ana-
log sound IF signal in, down to processed analog or
digital AF (baseband audio) out, is performed on a sin-
gle chip. Fig. 1–1 shows a simplified functional block
diagram of the MSP 44x8G.
The MSP 44x8G built-in stereo A/D converters offer a
S/N ratio of 95 dBA typ. The double stereo D/A con-
verters with analog volume and 0.125 dB steps make
use of the Micronas unique multibit Delta-Sigma tech-
nology, offering a dynamic range of 95 dBA typically.
The DSP processing is performed at a 48 kHz sample
rate, maintaining the full audio bandwidth of 20 kHz in
all MSP 44x8G signal paths.
The MSP 44x8G has been designed for the usage in
hybrid set-top boxes and multimedia applications. It
combines the function of a TV stereo decoder together
with an Audio I
