AD 9174 Question about JESD204B Operating Modes

Hello,

i have a question to the AD9174 Eval Board. Can i use the wideband mode (JESD mode 8) with 4000 MHz and 12 Bit for 2 real Signals (like I and Q) ? So that one Signal is the Output on the DAC0 and the other on the DAC1 or is with this wideband mode only the DAC0 the output.

My other idea is to use the complex wideband mode (JESD mode 22) so that i can use the dual link mode. And the outputs of my DAC0 and DAC1 are my "complex" I and Q Signals?

Thank you for your help.
