Can CDCE913-Q1 chips be written to death without using I2C, allowing 27M input and 24M output?

  • Hello,

    I'm not sure I understand your question. Can you add more details?

    Regards,

    Dear Hao

       Thanks for your support!

         See the figure below.

       

      The functions used are input 27MHZ CLK, OUTPUT 24MHZ CLK and MCU for I2C communication settings.           

      Question: 1,Can 27MHZ be used as input and 24MHZ output be fixed by MCU , power off;

                       2,then the MCU  removed;after power-on, and 27MHZ can be retained as input and 24MHZ output configuration ?

          Can you help confirm this use?

    Hi there,

    Sorry for the late response, I didn't really see your previous post because it was accidentally closed. So yes this is doable. You just need to write to EEPROM. Please refer to datasheet on more details. You can use the GUI as a starting point, as EEPROM writing can be complex.
