Please refer to the CS4932x/CS49330 Part Matrix
vs. Code Matrix (PDF) document available from
the CS49300 Web Site Page for the latest listing of
audio decoding/processing algorithms. The part
will also support PES layer decode for audio/video
synchronization and DVD Audio Pack layer
support. The CS49300 will support all of the above
decoding and PCM processing standards.
CS4931X - Broadcast Sub-family. The CS4931X
sub-family is targeted at audio decoding in the
broadcast markets in systems such as digital TV,
HDTV, set-top boxes and digital audio broadcast
units (digital radios). Specifically the CS4931X
sub-family will support the following decode
standards:
• Dolby Digital(AC-3) with Dolby Pro Logic
• MPEG-2, Advanced Audio Coding Algorithm
(AAC)
• MPEG-1, Layers 1, 2 Stereo
• MPEG-1, Layers 3 (MP3) Stereo
• MPEG-2, Layer 2 Stereo
• MPEG-2, Layer 3 (MP3) Stereo
The part will also support PES layer decode for
audio/video synchronization. The CS49310 will
support all of the above decode standards while
other parts in the CS4931X sub-family will decode
subsets of the above audio decoding standards.
CS4932X - Audio/Video Receiver (AVR) Sub-
family. The CS4932X sub-family is targeted at
audio decoding in the audio/video receiver
markets. Typical applications will include
amplifiers with integrated decoding capability,
outboard decoder pre-amplifiers, car radios and
any system where the compressed audio is
received in an IEC61937 format. Specifically the
CS4932X sub-family will support the following
decode standards:
• Dolby Digital(AC-3) with
Dolby Pro Logic
• Dolby Digitalwith Dolby Pro Logicplus
Cirrus Extra Surround
• Dolby Digitalwith Dolby Pro Logic II
• Dolby Digitalwith Dolby Pro Logic IIplus
Cirrus Extra Surround
• Virtual Dolby Digital
• MPEG-2, Advanced Audio Coding Algorithm
(AAC)
• MPEG Multichannel
• MPEG Multichannel with Dolby Pro Logic II
• MPEG Multichannel plus Cirrus Extra
Surround
• MPEG-1, Layer 3 (MP3)
• DTS Digital Surround
• DTS Digital Surroundwith
Dolby Pro Logic II
• DTS Digital Surroundplus Cirrus Extra
Surround
• DTS-ES Extended Surround(DTS-ES
Discrete 6.1 & Matrix 6.1)
• DTS Neo:6
• LOGIC5® (5.1 Channel, Max Fs=48kHz and
LOGIC7® (7.1 Channel, Max Fs=96kHz)
• VMAx VirtualTheater® (Virtual Dolby Digital)
• SRS TruSurround(Virtual Dolby Digital and
DTS Virtual 5.1Versions)
• SRS Circle SurroundI/II
• HDCD®
• Cirrus P.D.F. (Dolby Pro Logic 2Fs Decoder
and PCM Upsampler)
• Cirrus PL2_2FS (Dolby Pro Logic II 2Fs
Decoder and PCM Upsampler)
The CS49326 will support all of the above decode
standards while other parts in the CS4932X sub-
family will decode subsets of the above audio
decoding standards.
Except for the CS49329 which offers AAC support
this subfamily will offer integrated ROM support for
the AC-3 code, DTS code, Cirrus Original
Surround code and DTS tables. The CS49329 will
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
DS339F7
