UG-237
•
A stream conforming to the IEC60958 specification when the part receives audio sample packets with L-PCM encoded data (refer to
Figure 22).
•
An AES3 stream if the I2SOUTMODE[1:0] control is set to 0x3 (refer to Figure 23 and Figure 24). Note that AES3 is also referred to
as raw SPDIF. Each AES3 stream may encapsulate stereo L-PCM audio data or multichannel non L-PCM audio data (for example,
5.1 Dolby Digital).
•
Binary stream on the audio output pins when the part receives audio sample packets with non L-PCM encoded audio data (that is,
AC-3 compressed audio) and if the following configuration is used:
•
I2SOUTMODE must be set to 0x0, 0x01, or 0x2 for I
Figure 20, and Figure 21).
•
MT_MSK_COMPRS_AUD is set to 0.
Note that no audio flags are output by the part in that configuration. Each binary stream output by the part may encapsulate stereo L-
PCM audio data or multichannel non L-PCM audio data (for example, 5.1 Dolby Digital).
•
A stream conforming to the IEC61937 specification when the part receives audio sample packets with non L-PCM encoded audio
data (for example, AC-3 compressed audio). The audio outputs can carry an audio stream that may be stereo or multichannel audio
(for example, 5.1 Dolby Digital).
