ASRC Output Rate Bits (Bits[5:0])
These bits select the output conversion rate for the eight ASRCs.
Any asynchronous input to the ASRC is output at this rate. It
can be set by one of the 12 serial output channel pairs’ fS clock
signals (the LRCLK associated with their automatically assigned
serial port) or by the core’s fS,NORMAL, fS,DUAL, or fS,QUAD clock signals.
In the case of the ADAU1442, each output from the stereo
ASRCs can have a separate data output.
In the case of the ADAU1445, each output from the stereo
ASRCs can have a separate data output; however, all outputs
from Stereo ASRC[3:0] must be synchronous to each other, and
all outputs from Stereo ASRC[7:4] must be synchronous to each
other. The first group of ASRCs (Stereo ASRC[3:0]) takes its
output rate from the setting on the Stereo ASRC 0 output. The
output rate for Stereo ASRC[3:1] is automatically set to this rate,
ignoring the settings for the Stereo ASCR[3:1] outputs. The second
group of ASRCs (Stereo ASRC[7:4]) takes its output rate from the
setting on the Stereo ASRC 4 output. The output rate for Stereo
ASRC[7:5] is automatically set to this rate, ignoring the settings
for the Stereo ASRC[7:5] outputs.
In the case of the ADAU1446, which contains no ASRCs, these
registers do not affect system operation in any way and can be
ignored.
