CS49400 Family DSP

Multi-Standard Audio Decoder

Features

Description

The CS49400 Audio Decoder DSP is targeted as a market-

specific consumer entertainment processor for AV Receivers

and DVD Audio/Video Players. The device is constructed using

an enhanced version of the CS49300 Family DSP audio

decoder followed by a 32-bit programmable post-processor

CS49300 Legacy Audio Decoder Support

Dolby Digital EX^TM, Dolby Pro Logic II^TM

DTS-ES 96/24^TM, DTS 96/24^TM, DTS-ES

Discrete 6.1^TM, DTS-ES Matrix 6.1^TM, DTS

Digital Surround^TMand DTS Virtual 5.1^TM

MPEG-2: AAC Multichannel 5.1

MPEG Multichannel and Musicam

MPEG-1/2, Layer III (MP3)

DSP, which gives the designer the ability to add product

differentiation through the Cirrus Framework

programming

structure and Framework module library. Dolby Digital Pro

Logic II, DTS Digital Surround, MPEG Multichannel, and Cirrus

Original Surround 6.1 PCM Effects Processor (capable of

generating such DSP audio modes as: Hall, Theater, Church)

DTS Neo:6^TM, LOGIC7^®, SRS Circle

Surround II^TM

are included in the cost of the CS49400 Family DSP. Additional

Cirrus Extra Surround^TM, Cirrus Original

Surround 6.1 (C.O.S. 6.1)^TM

algorithms available through the Crystal Ware

Software

Licensing Program, give the designer the ability to further

THX Surround EX^TM, THX Ultra2 Cinema^TMdeliver end-product differentiation.

12-Channel Serial Audio Inputs

Integrated 8K Byte Input Buffer

Powerful 32-bit Audio DSP

The CS49400 contains sufficient on-chip SRAM to support

decoding all major audio decoding algorithms available today

including: AAC Multichannel, DTS 96/24, DTS-ES 96/24. The

CS49400 also supports

a glueless SDRAM/SRAM for

Large On-chip X,Y, and Program RAM

Supports SDRAM, SRAM, FLASH

memories

increased all-channel delays. The SRAM interface also

supports connection to an external byte-wide EPROM for code

storage or Flash memory thus allowing products to be field-

upgradable as new audio algorithms are developed.

16-channel PCM output

This chip, teamed with Crystal Ware
