S/PDIF Data
4.6.4.5
This One-Line Mode configuration can support up to 6 channels of DAC data 2 channels of ADC data and
2 channels of S/PDIF received data and will handle up to 24-bit samples at a sampling frequency of 48 kHz
on all channels for both the DAC and ADC. The output data stream of the internal ADCs can be configured
to use the CX_SDOUT output and run at the CODEC_SP clock speeds or to use the SAI_SDOUT data
output and run at the SAI_SP rate. The CODEC_SP and SAI_SP can operate at different Fs rates.
