AD9136 output polarity

Hello all,

I am working on a new design using AD9136 and ADRF6720 parts.

The connection between out0+/- of the DAC and I+/- of the modulator is straight but the out1 is "swapped" compare to the modulator Q+/-.

 

So just to check that I understood, by connecting directly out1+/- to Q-/+ of the modulator, I just need to invert the Q polarity using the MOD_CTL0 register of ADRF.

 

Thank you for the support.

 

Best,

 

Chris
