Output data of AD9129 is broken

When I tested with power on/off, sometimes RF output was broken.

I tested DLL mode and odelay of FPGA. Two method was the same result.

And when I reconfigured AD9129 repeatedly, this issue was occurred.

Could you guide me how to resolve this issue?

abnormal operation :

  • I set registers of AD9129.
