The following table shows the signals for AXI4-Stream audio streaming interfaces. The audio interface transports
24-bits L-PCM or 16-bits HBR audio samples in the IEC 60958 format. A maximum of 32
channels are supported.
The audio interface is a
32-bit AXI4-Stream master interface and runs
at the s_axis_audio_aclk clock rate.
