3.1.2 USB Audio AC-MB Settings

The serial interface clocks and data are provided from the USB interface. The sampling rate and format are determined by the USB audio class driver on the operating system.

The default settings for the USB audio interface are 32-bit frame size, 48kHz sampling rate, BCLK and FSYNC ratio is 256, and the format is time division multiplexing (TDM).

The AC-MB is detected by the OS as an audio device with the name TI USB Audio UAC2.0. The AC-MB audio setting for the USB mode of operation is illustrated in Figure 3-2.
