AFE58JD28: AFE58JD28 JESD Issue

Part Number: AFE58JD28

Tool/software:

Hi Team,

I used the AFE58JD28 chip to verify JESD. When I send lia data using the test mode the padding data given to me is not the cumulative number. But selecting test mode to send K28.5 shows BCBC, which is normal.




If I choose to skip ila, BC50H is also transferable. It's just that ila's transmissions are very strange and irregular.



Please advise.

Regards,

Josel

     When I send ila data using the test mode the padding data given to me is not the cumulative number. What do you mean by this ?

    Do you have any waveform or received data ? 

    What I understood is K28.5(BCBC) transmission is fine and BC50H using IDLE_MODE register is also working fine . Only the issue is on ILA sequence . Is that correct ?

    Hi Sachin,

    Yes, only the issue is on the ILA sequence

    The data is in the previous form, I'll resend it again in the attachment, when I use the test mode to send the ILA sequence (i.e. Register 74 15-13 bits written to 011), I get the result as attached by ila grabbing the data, ILA's data in the first frame is jumbled and irregular, and I'm checking the information that says that this data is supposed to be the cumulative numbers.



    When I set up to send BC50H using IDLE_MODE and enable ILA transmission disabled, BC50H can be transmitted normally.
