Hello,

 

Our customer has evaluated AD9914 using AD9914 Evaluation board. However the customer found phase noise degradation in a few minutes after power ON of the evaluation board. Please refer attached data. Do you have any idea about cause of this phenomenon?

 

Input Frequency : 1900MHz

Output Frequency : 187.35MHz

 

Best regards,

Akira
