Other Parts Discussed in Thread: DAC38J84, , LMK04828
I purchased DAC38J84EVM and connected it to the VC707.First, I downloaded the configured JESD204 to VC707.In accordance with the requirements in the manual, I programmed DAC38J84 and LMK04828 using the DAC3XJ8X GUI.After that, I read all the registers in the low level view, and I found that they were all 0xFF or 0xFFFF.Furthermore, in VC707, I found that DAC38J84 did not generate the corresponding clock signal and sysref signal.Therefore, DAC38J84EVM and VC707 did not achieve a successful connection.
I don't know why DAC38J84EVM was not successfully configured, so I come here to ask for your help.Below are some screenshots of the configuration process for your reference:

DAC3XJ8X GUI initialization parameter
After programming LMK and DAC, and reading all registers, they become FF and FFFF.
note：I can't change all the checkboxes and modifiable items in the GUI. All the parameters become maximum after I change them.For example, I changed the LMF to 442 and they became the values shown below:
Thank you for your help.
