Is it possible to use the signal of "I" and "Q" about the directions for DAC5688 and DAC5687, making it into a separate signal?
※For example, frequency is it being the same, being MAIN about "I", and using "Q" by other signals etc.
Moreover, is there any application note written about the register setting method in more detail than the information on a data sheet? (Are there any data which are consulted in addition to the following?)

Hi Satoshi,
The DAC5687 and DAC5688 can accept two independent data streams on channel A and B as long as you do not use the complex mixer. When complex mixer is enabled, the two data streams will be mixed and added. The output of the DAC will not be independent afterwards.
You may also refer to the app note below for more information on the DAC setup. If you have questions regarding a specific setup parameter and settings, I can also help you create a setup register file.
Thanks.
