INTRODUCTION
The CM9600 is a high performance, low power, dual I2S interface audio CODEC. First I2S interface can support dual mode: normal I2S and I2S with TDM (Time Division Multiplexing) interface. The TDM interface can transmit/receive up to 8 channels data. The transmitted data can from analog input or digital microphone input. Also the received data can to headphone output, line output or PDM output. Asynchronous Sample Rate Converter (ASRC) provides independent and asynchronous connections to different processors, such as an application processor, baseband processor or wireless transceiver(BT)
