One question for AD9269 digital interface.

Dear Sir:

 

 

                There is a register to set output voltage to 3.3V or 1.8V, as datasheet page 33 as below :

               it is strange to me that I think outputvoltage is determined by the applied voltage on DRVDD, not by a register setting

Or, if I connect DRVDD to 1.8V, and set output mode to 3.3V, is it okay to interface with 3.3V I/O in this case ?

 

 

Thanks

Best regards

 

 

Jason
