Hi,

UI Period is Unit Interval.

eg, If you want to transfer 10G rate, your actual line rate is 10.3125G due to 64b/66b encoding. In this case, your UI Period = 1/10.3125 ns.

Similarly, if want to transfer at 2.5G, your actual line rate is 3.125G due to 8b/10b encoding. In this case, your UI Period = 1/3.125 ns.

Hope this clarifies.

Thank you,
