JESD204 v5.1 - What is the payload of JESD204B at 12.5Gbps line rate?


What is the payload for JESD204B at 12.5Gbps line rate?


The payload is the data before 8b10b encoding.  

Therefore at 12.5Gbps the user payload is 8/10*12.5Gbit = 1.25Gbytes/s (per lane).

No other protocol overhead applies to JESD204, so the payload is 1.25Gbytes/s.   

(In Ethernet applications, for example, there are idle characters and header bytes which reduce the payload below 8/10ths of the line rate).
