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.

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.
