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

Justified digital audio format. DTS CDs are one

exception as they deliver compressed data

according to IEC60958.

Data delivery is:

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.
