    Hi Louis,

    DS280DF810 maxim EQ gain is at least 35dB at 12.9GHz. In your application 12.8Gbps or 6.4GHz nyquist gain is going to be lower. It would be best to use 4-ports s-parameter model of you media with DS280DF810 IBIS-AMI model to simulate your application. Additionally you can send us email at nasser.mohammadi@ti.com to describe your application in  more details. There might be other devices that may fit this application as well.
