Hi TI,
I would like to use the PCM9211 ADC as I2S slave, and received LRCLK/BCK/MCLK from external I2S master device (my DSP). Then the PCM9211 MPIO_B set as I2S AUX output to output the I2S data of the ADC to my DSP. Below is my EVM setting, but I cannot get I2S data output in MPIO_B. Only if I set the ADC clock source to XTI or DIR or AUTO, then the ADC I2S data only have output. However, this setting is not I want, I want to use my DSP I2S LRCLK/BCK/MCLK to drive PCM9211 ADC. could you advise how I need to do the setting in PCM9211 to fulfill my application?
Besides, my DSP output I2S LRCLK (48KHZ), BCK (3.072MHZ),MCLK(12.28MHZ) to PCM9211 AUX1 (MPIO_C), which already fulfill the PCM9211 ADC clock requirement. but I still cannot get ADC I2S data output from my AUX port (MPIO_B3).
Below is my connection image
If my connection is wrong, please teach me how to connect in order to use PCM9211 ADC as I2S slave and drive by external I2S clock source ( my DSP)
1) I2S CLK from my DSP need to connect to which port of PCM9211?
2) The PCM9211 ADC I2S output need to retrieve from which port of PCM9211?
thank you very much
