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.
