CS4932X/CS49330
Part Matrix vs. Code Matrix for AVR/Outboard Decoder-based Applications
1. CS4932X/CS49330: AVR/OUTBOARD
DECODER SUBFAMILY
For AVR codes, all compressed inputs are expected
to be packed according to IEC61937 while PCM is
delivered according to IEC60958 in I2S or Left-
Justified digital audio format. DTS CDs are one
exception as they deliver compressed data
according to IEC60958.
2. AVR/OUTBOARD DECODER-BASED
STANDARD RELEASE APPLICATION
CODES
2.1 Application Code Logo, Name,
Description, and Notes
• AAC - Multichannel MPEG-2 AAC (LC,
ADTS) decoder with 5.1 channel output.
Data delivery is:
I2S or Left-Justified Compressed Digital audio
according to the IEC61937 specification or
PCM according to the IEC60958 specification
and is typically delivered from a S/PDIF
receiver.
Expected CLKIN = 12.288 MHz (Oscillator Value)
DSPCLK = Refer to AN163 (Application Code
Dependent)
Standard Hardware Configuration: OUTPUTA1
(DSP is Slave to MCLK, DSP Masters SCLK and
LRCLK)
Refer to AN163 and its appendices for how to
control AVR/Outboard Decoder-based Standard
Release Application Codes that run on the
CS4932X Family and/or the CS49330.
AAS_PROL2 - Stereo MPEG-2 AAC (LC,
ADTS) with Dolby Pro Logic II decoder
offering up to a 5.1 channel output.
[®
ACEQ - Dolby Digitalwith Dolby Pro Logic
decoder and PCM input support. This code
features a 5 Channel, 5 Band Graphic Equalizer.
®
AC3 - Dolby Digitalwith Dolby Pro Logic
decoder and PCM input support. This code
features +/-12dB Tone Control.
®
The designer/manufacture should be aware that
obtaining and/or evaluation of any/all application
codes requires signing of a Crystal Ware Software
Licensing Agreement (CWSEA). Additionally, a
Crystal Ware Licensing Agreement (CWLA) must
be signed before any/all application codes may be
used in any production-level design. Please contact
your Cirrus Logic Sales Representative or FAE in
order to obtain the necessary contracts, application
codes and application notes.
Note: Tone Control is implemented as individual bass
and treble control on the Left, Right, and Center
output channels.
• AC3_CES - Dolby Digitalwith Dolby Pro
Logic decoder and PCM input support. This
code features Crystal Extra Surroundwhich
enables a 6.1 or 7.1 channel output.

enables a 6.1 or 7.1 channel output.
®
• DTS_NEO6 - DTS Neo:6PCM Processing
Enhancement which accepts a 2 channel input
and outputs up to 6.1 discrete channels in either
a Music or Cinema mode. Fs of PCM input
must be 48kHz, 44.1kHz or 32kHz.
Neo:6
• DTS_PL2 - DTS Digital Surrounddecoder
with Dolby Pro Logic II decoder.
[® ®
• DTS_PL2_REEQ - DTS Digital Surround
decoder with Dolby Pro Logic II decoder. This
code features user-programmable 2nd Order
IIR Biquads which are capable of offering Re-
EQfunctionality. Re-EQ coefficients are
NOT supplied by Cirrus Logic, Inc. Use of Re-
EQ technology requires a license from the THX
Division of Lucasfilm, Ltd.
[® ®
Note: Please refer to AN163 for more detail regarding
the differences between IBA and Full Download
codes.
• DTSR - DTS Virtual 5.1using SRS
TruSurround (DTS Digital Surround decoder +
SRS TruSurround Digital 5.1 Channel
Virtualizer Module). Offers ability to have
virtualized 5.1 channel output using only 2
speakers. The virtualizer can be disabled,
offering a full 5.1 channel output if desired.
®
• DVDA_BASS_MGR - DVD Audio Bass
Manager application code is capable
performing advanced bass management for 2
channel 192kHz PCM audio data or 6 channel
96kHz PCM audio data. This code is designed
for an AVR that is “SACD Multichannel or
DVD Audio Ready” via high performance
(192kHz) A/Ds.
• DPP - Crystal Digital Post-Processor 5.1
Channel Post-Processor features Tone Control,
Parametric EQ, and dual-precision bass
management. This code accepts a 5.1 channel
input to the CS493302-CL from the output of a
CS4932x Family DSP.
Note: Tone Control includes basic bass and treble
control for each full bandwidth channel. The
parametric EQ can not be changed after
kickstart. Delays are all channel.
• DPP8 - Crystal Digital Post-Processor 7.1
Channel Post-Processor features Tone Control,
Parametric EQ, and dual-precision bass
management. This code accepts a 7.1 channel
input to the CS493302-CL from the output of a
CS4932x Family DSP.

• THX - Home THX Cinema5.1 Channel Post-
Processor offers: Re-Eq, Timbre Matching,
Adaptive DecorrelationTHX Bass Peak
Limiter, Loudspeaker Position Time
Synchronization(all-channel delays), in
addition to tone control and parametric
equalization.
Note: The tone control includes basic bass and treble
control for each full bandwidth channel, including
Surround Back channel (Sb). The parametric EQ
can not be changed after kickstart. Delays are all
channel. Please refer to AN163H for more
information about the Home THX Cinema 5.1
Channel Post-Processor code.
• THX8 - Home THX Cinema7.1 Channel
Post-Processor offers: Re-Eq, Timbre
Matching, Adaptive DecorrelationTHX
Bass Peak Limiter, Loudspeaker Position
Time Synchronization(all-channel delays),
in addition to tone control and parametric
equalization. THX8 differs from the THX code
in the sense that it can post process
multichannel sources that have more than 5.1
discrete channels, such as DTS-ES Discrete 6.1
streams.
• TEX - THX Surround EX5.1 Channel Post-
Processor offers all of the post-processing
features of the THX code, however TEX also
offers the Surround EX module. The Surround
EX module performs a matrix decode on Ls and
Rs, using a Dolby Pro Logic decoder in 3
Channel Stereo mode, to create an additional
back surround channel. This surround back
channel is then copied to the output channels of
Sbl and Sbr in order to give a 7.1 channel
output.
Note: The tone control includes basic bass and treble
control for each full bandwidth channel, including
Surround Back channel. The parametric EQ can
not be changed after kickstart. Delays are all
channel. Surround EX decoding should only be
enabled when material is Dolby Surround EX
encoded. Please refer to AN163H for more
information about the THX Surround EX 5.1
Channel Post-Processor code.
• TEXO - THX Surround EX5.1 Channel
Post-Processor offers all of the post-processing
features of the TEX code, however TEXO also
offers extended all channel delays (up to 105ms
on all channels).
Note: The tone control includes basic bass and treble
control for each full bandwidth channel, including
Surround Back channel (Sb). The parametric EQ
can not be changed after kickstart. Delays are all
channel. Please refer to AN163O for more
information about the Home THX Cinema 7.1
Channel Post-Processor code.
Note: The tone control includes basic bass and treble
control for each full bandwidth channel, including
Surround Back channel. The parametric EQ can
not be changed after kickstart. Delays are all
channel. A 1MBit External SRAM (70nS) is
required to be connect to the CS49330 in order
for this code to function. Surround EX decoding
should only be enabled when material is Dolby
Surround EX encoded. Please refer to AN163H
for more information about the THX Surround EX
5.1 Channel Post-Processor code.
