Hi Experts,
we have used the two redriver on the path & it is not working, eye is always closed at 8Gbps when we run PRBS31
Test method/channel: FPGA --> Redriver --> Redriver --> looped back.
FYI : tested with 1G, It worked & 8Gbps is working at PRBS7 (with small eye opening) .
We have tried fine tuning the equalizer, But it didn't help to solve the issues.
As per our test method, 4 times redriver used in the path, Will redriver (DS80PCI810NJYR) suggest to use 4 times.
Please provide your advice
Regards
Karthik
