    Hi Sri_apex,

    Are you using a crystal connected to the CLKIN and CLKOUT pins or an external clock source? If you have an external clock source, try using that to see if anything changes.

    Please send the specifications of the crystal you are using.

    How are you determining that the crystal oscillator is not working? Are you not able to communicate with the part? When powering the ADE7878, the IRQ1 pin should go low once the part is powered, are you seeing this transition happen?

    Regards,

    Dlath

  • Hi David,

                I checked IRQ1 pin after Reset condition, It's not go to low. Then I checked CLKIN & CLKOUT is came 16 MHz.

    Hi Sri_apex,

    Are you able to test another ADE7878 to see if you have the same issue?
