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 Digital™ with Dolby Pro Logic
decoder and PCM input support. This code
features a 5 Channel, 5 Band Graphic Equalizer.
®
AC3 - Dolby Digital™ with 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 Digital™ with Dolby Pro
Logic decoder and PCM input support. This
code features Crystal Extra Surround™ which
enables a 6.1 or 7.1 channel output.

CS4932X/CS49330
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.
• EFF - (a.k.a. C.O.S. - Crystal Original Sound)
Reverberative and delay effects code for stereo
to multichannel effects processing and +/-12dB
Tone Control. This code allows for designers to
generate such DSP modes as: Concert Hall,
Theater, Jazz Club, etc.
Note: Tone Control is implemented as individual bass
and treble control on the Left, Right, and Center
output channels. There is an output mixer for
each channel allowing for multiple speaker
configuration settings. However, conventional
downmixing is not applicable in the effects code.
• EFF_REEQ - Crystal Original Sound with +/-
12dB Tone Control in addition to user-
programmable 2nd Order IIR Biquads which
are capable of offering Re-EQ™ functionality.
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: Tone Control is implemented as individual bass
and treble control on the Left, Right, and Center
output channels. Re-EQ is implemented on only
the L, C, and R channels. There is an output
mixer for each channel allowing for multiple
speaker configuration settings. However,
conventional downmixing is not applicable in the
effects code.
• EFFI - Internal Boot Assist (IBA) program for
loading Crystal Original Surround code
Note: There is an output mixer for each channel
allowing for multiple speaker configuration
settings. However, conventional downmixing is
not applicable in the effects code. Please refer to
AN163 for more detail regarding the differences
between IBA and Full Download codes.
• HDC - Pacific Microsonics HDCD™ PCM
Enhancement offers upsampling and resolution
enhancement.
Note: Autodetection for HDCD is a two step process,
please see AN163D for details.The HDCD code
is capable of accepting and autodetection HDCD
and non-HDCD encoded PCM stereo inputs with
an Fs from 32 kHz to 96 kHz. HDCD processing
is only available for input streams 48kHz and
lower. The HDCD is also capable of upsampling
32 kHz to 64 kHz, 44.1 kHz to 88.2 kHz, and
48kHz to 96kHz.
• LG7 - Logic 5™ (previously called “Logic 7”)
is a PCM Enhancement algorithm created by
Lexicon, a Harman International Companym
which accepts a 2 channel input and outputs up
to 5.1 discrete channels. Fs of PCM input must
be 48kHz, 44.1kHz or 32kHz..
• LG7_7DOT1 - Logic 7™ is the next generation
PCM Enhancement algorithm from Lexicon, a
Harman International Company, which accepts
a 2 channel input and outputs up to 7.1 discrete
channels. Fs of PCM input must be 96kHz,
88.2kHz, 64kHz, 48kHz, 44.1kHz or 32kHz..
®
• MPEQ - MPEG Multichannel with Dolby Pro
Logic decoder. This code features a 5 Channel,
5 Band Parametric Equalizer
®
Note: The MPEQ code ONLY supports the following
MPEG streams: MPEG-2, Layer 2 (with and
without extension). MPEG-2 Low Sampling
Frequencies are currently not supported. Please
refer to AN163 for more details on stream
support.
