Part Number: LMK04828
Other Parts Discussed in Thread: ADS54J69

Dear TI experts,

My customer now tests LMK04828 with ADS54J69.

but they have a trouble verifying the operation of LMK04828.

Could you review the schematic and find the reason of no output of LMK04828?

- They drew their schematic exactly same as ADS54J69 EVM.

- The outputs to Xilinx (2x100MHz) are detected, but CLK/SYSREF to ADS54J69 is not detected.

Please check the schematic and settings, and guide me the way to test.

Best regards,

Chase

    Hi Chase, 
    From what I am able to see, I don't see any immediate issue with the schematic...
    It is very blurry though, if you can attach a cleaner searchable pdf, that would greatly by appreciated. 


    Also, can you please attach customer config file? Preferably a .tcs file? This can also help pinpoint the root cause of not seeing any outputs. It is very odd customer is not seeing no waveform at all.

    Regards, 

    Vicente
