 Choose the data rate (in Gbps), reference clock frequency (in MHz), and SerDes width combination. Your selection displays in the GUI.
Data rates higher than 10.3125 Gbps are only supported in C4, I4, C4L, I4L speed grades.

Some settings apply to all lanes in a quad. The software prompts you with a message when you change the resource to a lane in another quad.

1 Efinity patch 2024.2.294.2.x only supports the presets listed. Other data rates, reference clock frequencies and SerDes width combinations will be supported in later versions of the software.
