Stratix 10 - TX PAM4 2 x 51Gbps with SMA Design Example 18.1

Hello, I have a Stratix 10 TX board and I am testing the design example "Stratix 10 - TX PAM4 2 x 51Gbps with SMA Design Example 18.1", provided in this link

https://www.intel.com/content/www/us/en/design-example/715120/stratix-10-tx-pam4-2-x-51gbps-with-sma-design-example-18-1.html

I would like to download the User Guide related to this design example ("Intel Stratix 10 TX PAM4 2 x 51Gbps with SMA Example Design 18.1 User Guide" in the section "Documentation"), but the link does not work. Could somebody send me the pdf via email or private message?

Thanks in advance,
