Flexible Audio Routing Matrix—Input Side
Up until this point in the audio signal flow, all signals can be
asynchronous to each other. However, before entering the DSP
for processing, the signals must be synchronized to the same
clock. Therefore, on the input side of the routing matrix, the
input channels can be routed, if desired, to the ASRCs for
sample rate conversion. The input side of the routing matrix is
represented in Figure 39 as a large gray box.

Figure 39. Flexible Audio Routing Matrix—Input Side
As shown in Figure 39, Input Channels[23:0] are hardwired
to DSP Inputs[23:0]. However, Input Channels[23:0] are also
available at the input side of FARM to be routed to the ASRCs.
Note that there are 13 channel pairs available on the left side of
FARM (12 input channel pairs and one S/PDIF Rx pair) and
eight channel pairs coming from the top (DSP-to-ASRC pairs).
These make up the 21 input channel pairs available to the input
side of the routing matrix. In the lower right, there are eight
channel pairs output from the routing matrix (inputs to the
ASRCs). These make up the eight output channel pairs available
to the input side of the routing matrix. Because audio is always
routed in pairs, a one-to-one connection can be made between
any input pair and any output pair. Therefore, any input channel
pair, S/PDIF Rx channel pair, or DSP-to-ASRC channel pair can
be connected to any ASRC input pair. Any combination is
possible, as long as a one-to-one relationship is maintained.
Note that most applications require sample rate conversion of
the S/PDIF Rx signal.
In the case of the ADAU1445, there are two 8-channel ASRCs.
Therefore, Stereo ASRC Input Pairs[3:0] (composed of Channel 0
to Channel 7) correspond to the first ASRC (Stereo ASRC[3:0])
and must be synchronous to each other. Stereo ASRC Input
Pairs[7:4] (composed of Channel 8 to Channel 15) correspond
to the second ASRC (Stereo ASRC[7:4]), and must be synchronous
to each other.
In the case of the ADAU1446, there are no sample rate converters;
therefore, after the automatic channel assignment, the stereo input
pairs are hardwired to the DSP core and the input side of the
routing matrix is not used. This is shown in Figure 40.
