AFE58JD28: AFE58JD28 JESD Issue

 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.

Hi

I read the FPGA registers and it shows that it's at the stage of transmitting data, but I'm using the test mode to send the BC50 and the data on the two channels is not correct, do I need to adjust the latency of the LMK048?

Ila sequence is something like this . This will come CGS Phase after deasserting sync signal.

Hi Sachin,

Yes, I'm already in the ILA phase and the SYNC signal has been pulled high, the fill data for the first frame of ILA is not cumulative

What do you mean by ILA is not cumulative ?  

 I'm checking the information that says that this data is supposed to be the cumulative numbers. - Can you share this document ?

JESD 204B 调试手册 （ti.com.cn）Page 11 of this manual shows that the first frame of the ILA is a cumulative number starting at 00
