HMC6300 Baseband common mode voltage level

Hi,

I am using HMC6300 in my application. By baseband output from DAC is having a common mode voltage level of 2.7V. But HMC6300 datasheet gives a typical common mode voltage level of 1.6V.

 

Does that mean I have to bring down my baseband common mode voltage from 2.7V to 1.6V?

 

Also I want to know if can I do AC coupling for baseband input or it has to be DC coupled only?

 

Regards,

Kiran
