    Mick,

    Do you have more information about the customer application? what is the MCLK frequency? what is their Fs ? data format etc...

  • In reply to Steve-Wilson:

    hello Mick, I will need to know the clk frequencies if you want me to look over the customer's configuration

    Hi Wilson:

         customer used internal 300K  frequemce,

  • In reply to Steve-Wilson:

  • In reply to mick li:

    Mick,

    The 300khz internal oscillator is not available as the input for the PLL. What is the MCLK frequency provided? What is the Desired Fs for Port1?

    best regards,
