Aurora 8B10B txoutclock rate

[msauer75]

Hi,
in our design (Artix-7 200) I use an Aurora 8B10B core with the following parameters:

I expect a tx_out_clk rate of 100MHz but it seems that isn't it. What is the correct clock rate?
Thank you for your help.

The 100 MHz setting you have are for initialization and the dynamic reconfiguration ports. The data path is based on the GT Refclk which is 125 MHz in this case.

2,500,000,000 bps/120,000,000=20-bits ==> with 8b10b => 2-bytes (the lane width)
