DAC5688EVM and TSW1400EVM tend to be used and it is going to output the following frequency.
Is it right at an attached register setup?
If a mistake occurs, please let me know.

[Request specification]
- Use PLL (divide ratio: x8).
- 100MHz CLK input
- DAC input are -38.64MHz by an I/Q input.
(the 13th page of the following web)
- A NCO input is 102.5 MHz.
⇒It is going to mix and is going to output 63.86 MHz.

※A setup of TSW1400
- It is DAC CMOS firmware download.
- Single tone
- Center frequency: -38.64 MHz(Complex)
- 800Msps
- 2's Comp
[About a background and register data]
- There is no DAC5688EVM at hand and it measured by DAC5689EVM.
(DAC5689 is the same except that there is no PLL compared with DAC5688)
- DAC5689EVM has been outputted normally.
The GUI register data of DAC5689EVM is attached.

※About the data of the question register
⇒Compared the register of DAC5688 and DAC5689, and it wrote it in order to carry out the same output by DAC5688EVM (PLL use).
