DAC38J84: Input Data Format to DAC

Part Number: DAC38J84

Hi 

I am using DAC38J84

I am using only 2 outputs out of 4 DAC outputs.

Now I need to send LFM Data on all the Lanes

Inputs : I1, Q1, I2, Q2 

(I1 -- Real Component for a particular Frequency F1) 

(Q1 -- Quadrature Component for a particular Frequency F1) 

(I2 -- Real Component for a particular Frequency F2) 

(Q2 -- Quadrature Component for a particular Frequency F2) 

 

Output :

Connector A : I1 + Q2

Connector B : I2 + Q2

Connector C, D : open   

I am using NCO frequency of 300 MHz.

In the NCO mixing the I and Q components are already mixed. So how to get the proper LFM (I1 + Q1) at the output ??
