AD9162  : DIGITAL MODULATION

Hello ,

 

I have a question about onfiguring for DIGITAL MODULATION.

Do I need "Modulus NCO Mode" to upconvert the baseband I/Q data to RF signal ?

When the relation of Fdac and Fcarrier is 2^N multiple, the "B" factor is zero in the equation (1) in P.69 of the datasheet.

Then this (1) equation could not satisfy.

I think in this case, I should use integer NCO.

Can I up-convert the baseband I/Q data to RF signal using integer NCO ?

If not, please let me know how to onfigure NCO when ths Fdac and Fcarrier has 2^N multiple relation.

 

Best regards,

ysuzuki
