What could cause Cyclone V GX transceivers to slowly degrade then fail over time

We have a system where some lanes of an 8-lane receive-only 2.3 Gbps interface first become more susceptible to poor signal integrity (smaller eye opening) and eventually don't lock under any signal ...

Hi,

As I understand it, you have some inquiries realted to the potential degradation of the CVGX RX. For your information, if the device is operating under the condition following the datasheet specs ie power supplies, signal voltages and etc, I am not aware of degradation of CVGX XCVR. I think you might need to further look into potential ESD or other on-board condition ie power supplies stability which might lead to the device damage.

Please let me know if there is any concern. Thank you.

Best regards,
