1.2 Introducing the CDB48500-USB Customer Development Kit
The CDB48500-USB kit is composed of the CDB48500 customer development board and the CDB USB
MASTER Control board. The CDB48500 provides a practical platform for emulating a typical multi-channel
audio system application. The CDB USB MASTER is a USB control board used to interface the host PC to the
CDB48500 board, and convert GUI commands into the serial control protocol required for configuring the
CS485XX DSP, (2)CS42448 codecs, and CS8416 S/PDIF receiver ICs.
