DS583F1
This One Line Mode configuration #3 will support up to 6 channels of DAC data, 6 channels of ADC data and 2
channels of S/PDIF received data and will handle up to 20-bit samples at a sampling frequency of 48kHz on all
channels for both the DAC and ADC. The output data stream of the internal and external ADCs is configured to use
the CX_SDOUT output and run at the CODEC_SP clock speeds. One Line Mode #2, which supports 24-bit sam-
ples, is not supported by this configuration.
