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. 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. 2.
