WebNov 17, 2024 · The early InfiniBand could use 8 bits for every 10 bits it sent — so called 8b/10b encoding — but with FDR InfiniBand and later the more efficient 64b/66b encoding could deliver 64 bits for every 66 bits sent. If you work encoding backwards from the lane throughput, you can calculate the clock frequency of the SerDes, which we have done.
