ADAU1373
MIX/MUX
The ADAU1373 provides very flexible mixing and multiplexing
of the digital signals to and from the DSP and to and from the
codec/Digital Audio Interface A/Digital Audio Interface B/
Digital Audio Interface C.
The input mixing and routing matrix allows the digital data from
Digital Audio Interface A, Digital Audio Interface B, and Digital
Audio Interface C, as well as the ADC and digital microphone,
to be selected or mixed to any of the DSP input channels (that is,
DSP Channel 0 to DSP Channel 4). Similarly, the output mixing
and routing matrix allows the data from DSP Channel 0 to DSP
Channel 4 to be mixed and routed to Digital Audio Interface A,
Digital Audio Interface B, and Digital Audio Interface C, as well

as DAC1 and DAC2. The digital volume controls on each of the
inputs, as well as the outputs, can be used to adjust the levels. The
soft mode allows the volume to be updated for clickless operation.
The routing matrix also allows the data to be looped back from
the internal ADC to the DACs or from Digital Audio Interface A
to Digital Audio Interface B or Digital Audio Interface C.
For recording purposes, the data from the ADC or the digital
microphone can be sent to Digital Audio Interface A, Digital
Audio Interface B, and Digital Audio Interface C. Similarly, for
playback, the data from the ports can be sent to the DACs and
then to the analog outputs. The mixing block allows complete
record and playback datapaths.
