1.7.3e Setup 11
Using the on-board crystal oscillator, AUDIO MCLK, a DSP connected to DSP I/O HDR
masters the subclocks for the DAC and provides data to the DAC. Using the on-board
crystal oscillator, AUDIO MCLK, the CS42406 ADC masters its subclocks and are output
onto DSP_ADC_LRCK and DSP_ADC_SCLK. The subclocks for the DAC are input via
DSP_DAC_LRCK and DSP_DAC_SCLK. This allows independent control of the sample
rate for the ADC and DAC. For implementation of this setup option, set DIP switch S4
(SW[3:0]) to ‘1011’b.
