FMCOMMS1 Start-up Signal Issue

Hi,

 

I use FMCOMMS1 with KC705. I use reference FPGA design and drivers (C codes) without out any problem. But, During initialization of the FMCOMMS1 a single tone signal is generated. I set the DAC data format as twos complement and I send DAC 0s in both channel. But the signal stays at the ADF4351 frequency.

 

What should I do to avoid from this signal?

 

Thanks,

Muhammet
