The AD9152 has no waveform output

Hi aioea

I could confirm that AD9152 in Mode 5 was working in AD9152_FMC_EBZ with ADS7 which is our evaluation board.

Are you using this type of ADI evaluation platform or your own designed board? 

If you are using your own board,  you  need to go through the process described in the data sheet for setting LMFC_delay.  You can leave LMFC_var set to 0xA.  If you don’t want to perform the power cycle testing as described in the DS (“Link Delay Setup” “Without Known Delays” section), you can just “sweep” the LMFC_delay setting  and determine which ones provide a stable output and deterministic latency and then pick same value in the middle of the range of “good” values.

Thanks,

Hello, thank you for your answer.

My LMFC_var already set to 0xA,and 0x470,0x471,0x472,0x473  get 0x0F,So I don't think it's the JESD204B link have some problem.

Sorry, I didn't describe it accurately. I can get the correct frequency on the spectrometer, but the amplitude is extremely low (-50dbm).

Also, when I use DC test mode, I get no output.

Do you have any good suggestions? thank you
