AD1938 Clock

hi

I am design broadcasting equipment and am using the ad1938 for the audio of the system

i have an external clock (12.288Mhz crystal) connected to the MCLKI  but i would like to just use that for the ADC  and use the BCLK from another device for the DAC .

i tried this is standalone mode and the ADC and DAC were not in sync, and now am using a microcontroller and i still can seem to the the system with with the different clocks

could you please advice me on if it can be done in standalone mode or how should i configur the registers ?

thanks

  • I'm using a 12.288Mhz crystal Oscillator

     

    The system is bi-directional ,I  am using the same product to send the audio

    So I am sending from the ADC of product1 to the DAC of product2

     

    I want too use the MCLK from the oscillator for just the ADC but then use the LRCLK for the DAC  so that the clock of the DAC in product 2 can be the same as the ADC of product 1

     

     

    I hope that's enough information for you to help me

     

    Thanks
