CS49330 - General Purpose, Car Audio
Processor, PCM Effects & Multichannel Post-
Processing Device. The CS49330 sub-family is
targeted at any system that may require post
processing or multichannel effects processing, a
general
Multichannel, MP3, decoder or PCM effects
processor or mixer, or for car audio applications.
Typical applications will include multichannel
amplifiers, outboard pre-amplifiers, HDTVs and
car radios. Specifically the CS49330 sub-family
will support the following:
•
•
DS339PP4
Cirrus Digital Post-Processor, Home THX
Cinema
Channel Post-Processors
Any general purpose application which only
requires MPEG Multichannel; MPEG-1, Layer
3; MPEG-2, Layer 3*, or C.O.S. PCM Effects
Processor. (MPEG-1, Layer 3 and MPEG-2,
Layer 3 are only available for applications
where serial or parallel bursty elementary
stream data is available. MPEG-1, Layer 3

This sub-family will continue to grow as more post
processing algorithms are supported.
This data sheet covers the CS49300, CS4931X,
CS4932X and CS49330 sub-families and devices.
These parts are identical from an external electrical
perspective. Internally, each part has been tailored
for supporting different decoding standards. For
this document individual part numbers have been
replaced by CS493XX if the description applies to
the entire CS49300 Family DSP. If a description
only applies to a particular sub-family, CS49300,
CS4931X, CS4932X or CS49330 will be used.
When CS49300, CS4931X, CS4932X or CS49330
is used, this should be interpreted as applying to all
parts within the particular sub-family or a
particular device.
audio decoding is only available for IEC61937-
packed MP3 data.)
