require an external download for all applications

but will still support the DTS tables on chip.

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

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.
