General Description
The ALC5640 is a high performance, low power, dual I2S interface audio CODEC. Dual I2S interface can connect to different devices and let the ALC5640 to be an Audio Hub. Each device can pass through the Audio Hub and then perform as input or output application. Asynchronous Sample Rate Converter (ASRC) provides independent and asynchronous connections to different processors, such as an application processor, baseband processor or wireless transceiver(BT).
