The customer is evaluating HMC439QS16GE.
But output signal characteristics is different with the datasheet.

Please give me advice about the following questions.


(1) Why the output signal voltage is 0.5V offset?

     Please tell me the occurring cause of this phenomenon.


(2) Vnu and Vnd voltage range was 3.5V to 4.5V.

     Why the voltage range is not 3V to 5V?


Please see the attached files.
