CS493302-IL

Multi-Standard Audio Decoder Family

Cirrus Logic 

CS49300 Family DSP

targeted at any system that may require post

processing or multichannel effects processing, a

general purpose MPEG Stereo, MPEG

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:

• Cirrus Digital Post-Processor, Home THX

Cinema® and THX Surround EX™ 5.1 and 7.1

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

audio decoding is only available for IEC61937-

packed MP3 data.)

• Multichannel Effects Processing

• General purpose broadcast application that

only requires MPEG-1 Stereo (Layers 1, 2, or

3) and MPEG-2 Stereo (Layers 2 or 3)

• Car Audio Post-Processor

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numbers have been replaced by CS493XX if the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.
