    Hi,
    

    I am looking to implement an ASRC in the I2S Demo provided in the ADSP-21479 code examples.
    

    The system :
    

    Input BCLK = 12.38 MHz, SCLK = 48 KHz
    

    And I want up sample rate the Output to be 192 Khz.
    

    I found this example in the website
    

    ez.analog.com/.../faq-asrc-tdm8-example-code-for-adsp-2148x
    

    , but I don't know how to modify it for my needs.
    

    Thanks.

      Hi ,
      

       
      

      Apologies for the delay in response.
      

       
      

      From your query we suspect you are trying to implement ASRC in "21479 AD1939 I2S C Sampled-Based Talkthru" available in ADSP-21479 code examples. Please confirm whether our understanding is correct.
      

       
      

      If so, please find the SRC in I2S example code available for ADSP-21479 Ez-kit from the below mentioned VDSP installation path. Please refer this code and modify the init1939viaSPI.c to use 192KHz sample rate.
      

      [Installation directory]\Program Files (x86)\Analog Devices\VisualDSP 5.1.2\214xx\Examples\ADSP-21479 EZ-Board\SPDIF to Analog TalkThru with SRC (C)
      

      

      Regards,
      

      Divya.P
