Part Number: ADS52J90EVM
Hello support team,
Our customer is now evaluating using ADS52J90EVM.The register 0x173 of LMK04826 can not be written with the GUI software of ADS52J90EVM.
I have two questions.
1. What is the POR DEFAULT value of register 0x173 of LMK 04826?2. How can I change the register value of 0x173 in the GUI of ADS52J90EVM?
Best regards,M. Tachibana
In reply to Olu Sodipe:
I'm sorry to my late reply.
Our customer tried register settings that you taught, but no output signal appeared at all.We do not know what is the problem.Could you please check whether it works with the config file attached this thread in your evaluation environment?

In reply to Masanori Tachibana:
How is the situation?The customer and I are waiting for your reply.
When you say that no output signal appeared at all, do you mean that there was no clock output? No SYSREF output?
Your PLLs should be locked with the desired clock frequencies if you modify the LMK's registers as I explained in my last post after running your attached script.
Yes, there was no clock output and SYSREF output, even though PLL1 and PLL2 are locked.(D3 and D4 of LEDs light up.)
The registers have been changed as you taught.I want you to check whether you get expected output in your evaluation environment using the config file attached to the previous post.
I apologize for uploading a different config file.I will reupload the config file that did not work in the customers environment.
Could you please check in your evaluation environment?
Thanks for your checking quickly.
When our customer run with the config file, output signals are seen for a moment , and after then no signal is seen at all.What is the difference from your evaluation environment?
What version of the GUI is yours?The customers version is as follows. ADS52J90 EVM Version 2.8 Builddata 11/04/2015
And is there a relation with the revision of ADS 52J90 EVM?
That is the right version of HMC-DAQ GUI and there is no relation or issue with board revisions for the ADS52J90 EVM.
I think at this point you need to debug the LMK to verify full board functionality. Try these steps;
That should help narrow the problem down a bit.
