with modified specifications.
For a brief history survey, please see appendix “MSP 3410 B Technical Code History”.
The present document is version 0.8. Revision bars indicate significant changes to
revision 0.7.
1. Introduction
The MSP 3410 B is a single-chip Multistandard Sound
Processor for applications in analog and digital TV sets,
satellite receivers and video recorders.
The MSP-family, which goes back to the MSP 2400,
demonstrates in an impressive way the progressive de-
velopment towards highly integrated ICs, offering more
and more features and flexibility. The development of
the MSP 2410 included an automatic gain control but re-
duced the amount of external components. The MSP
2410 reached a high level of performance and is the ba-
sis for the new generation.
The MSP 3410 B increases function integration in a
spectacular way. By including the MSP2410 as a library
cell and combining it with AD/DA converters and high
performance digital signal processing, the chip offers a
wide range of features. The complete TV-sound-proces-
sing, starting at the Sound-IF domain, will be performed
by one single IC. The inputs of the IC are analog audio
signals in baseband and at intercarrier position. The
MSP 3410 B covers the sound processing of a wide
range of TV-standards. Some examples are listed in
Table 3–1.
The MSP 3410 B is produced in 1.0 µm CMOS technolo-
gy and is available in 68-pin PLCC and in 64-pin PSDIP
packages.
