EDC issue

Dear All,

I am using AEL 2005 PHY in HTG-FMC-SFP-PLUS card that is further interfaced with FPGA (10 G XAUI and MAC core design).

When i test all the internal loopback (PMA,PCS, or PHY) it works better. But when i use external loop back via EDC connection breaks  exact after 4 minutes and data transmission between SFPs got stuck.

Any suggestions please

Re: EDC issue

What is EDC? What is the role of the EDC?

Please provide the core status details during the failure.

Re: EDC issue

How did you resolve the issue? I encountered the same issue on the same platform (HTG-FMC-SFP-PLUS).

I did the internal loopback perfectly. However, when performing external loopback with twinax cable, the communication was stuck after five minutes.

 

Please help me
