CS4932X/CS49330 Part Matrix vs. Code Matrix for AVR/Outboard Decoder-based Applications 1. CS4932X/CS49330: AVR/OUTBOARD DECODER SUBFAMILY
2. AVR/OUTBOARD DECODER-BASED STANDARD RELEASE APPLICATION CODES For AVR codes, all compressed inputs are expected to be packed according to IEC61937 while PCM is 2.1 Application Code Logo, Name, delivered according to IEC60958 in I2S or Left-JusDescription, and Notes tified digital audio format. DTS CDs are one excep• tion as they deliver compressed data according to IEC60958.
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)
