4.1.1 Audio Serial Interface Settings

The AC-MB provides the digital audio digital signals to the evaluation module from the universal serial bus (USB), optical, stereo jack, and external audio serial interface (ASI) header. Figure 4-1 shows a block diagram of the ASI routing on the AC-MB.

Switch SW2 on the AC-MB selects the audio serial bus that interfaces with the TAA3020EVB. Next to switch SW2, the AC-MB has a quick reference table to identify the audio serial interface source options and switch settings. The AC-MB acts as the master for the audio serial interface, with three different modes of operation: USB, optical or analog, or external ASI.
