Description
The I2S (Inter-IC-Sound) bus is the standard interface for connecting audio devices, such as audio codecs. The USB Audio/Video (AV) Device Class Definition describes among other things the methods used to communicate with devices containing sound-related functionality. This includes digital and analog audio data with its associated metadata and the functionality used to control the audio environment, such as volume controls. Microchip USB hubs provide a bridge from USB to an audio device codec via I2S. These devices support only USB Audio Device Class Specification v1.0. The I2S interface is a five-wire connection to the ADAU1961 codec. There is sufficient configuration flexibility to change the settings of the Analog Devices ADAU1961, or to implement a different codec. While the audio data to and from the audio codec is through the I2S interface, USB Audio Device control data is transferred through the I2C (master) interface of the hub.
