DAC38J84 NCO and Complex Mixer routing

Expert 1545 points
Other Parts Discussed in Thread: DAC38J84

Hello 

I would like to use the DAC38J84 in the following manner: 

DAC A and DAC B output NCO AB and NCO CD (two tones)

DAC C and DAC D 100MHz BW complex modulation +/-100MHz Complex BW around DC

Is it possible? can I route the NCO CD outside and still have the data around DC without using the complex mixer CD? 

See the drawing below (I hope it's clear)

Thanks
