AD9363: calculate RMS power from RX I and Q samples

My software captures some I and Q samples from RX ports via LVDS interface, I need to calculate the average RMS power of the samples. To calculate the voltage of the sample, I would use the below formula

 

Vsample = sample_code * Vreference / ((2^Nbit - 1) * root_square(2))

where Nbit is 11, is it right?

what is the value of Vreference for the AD9363?

 

Thanks and Regards,

Ramon
