FLEXIBLE AUDIO ROUTING MATRIX (FARM)
The routing matrix distributes audio signals among the serial
inputs, serial outputs, ASRCs, S/PDIF receiver and transmitter,
and DSP core. This simplifies the design of complex systems
that require many inputs and outputs with different sample
rates. It also allows signals to be routed in hardware, instead of
in software.
Routing Matrix Block Diagram
Figure 36 shows an overview of audio routing in the ADAU1442/
ADAU1445/ADAU1446 and details the interaction among the
S/PDIF I/O, serial I/O, ASRCs, and DSP via the routing matrix.
To reduce the complexity of the system, audio signals are routed
in pairs. Therefore, in Figure 36, each solid line represents a
stereo pair of audio signals. The corresponding channel
numbers are written above the lines. The dotted lines at the
bottom of the diagram represent clock signals. The two large gray
boxes represent the flexible audio routing matrix, in which one-to-
one connections can be made between any input and any output.
The signal routing is fully implemented in hardware.
System Delay
Routing data through the serial ports, routing matrix, ASRCs,
and DSP core results in a brief delay between the time when an
audio sample is input to the IC and when it is output. If the DSP
is programmed to simply pass serial inputs to serial outputs with
no sample rate conversion or additional processing, the minimum
observed delay of an audio sample from the SDATA_INx pin to
the SDATA_OUTx pin is equal to four sample periods. At a sample
rate of 48 kHz, this corresponds to 83 μs. The system delay increases
as sample rate conversion or additional processing is implemented
in the system.
