CycloneVgx transreceiver speed max.

Hello!

I'm looking on the site Terasic the cyclone gx starter kit. (http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=830)

In their specification is written that the transceivers working to 3.125 Gsps.

The card is equipped with a Cyclone V GX 5CGXFC5C6F27C7N, but the datasheet shows that the speed grade 7 works up to 2.5Gbps (see image).

Can someone help me to understand the max speed of the transreceiver?

Best Regards, Luca

    Speed Grade of Transceiver is 6 so 3.125 Gbps

    5CGXFC5C-6-F27C7N

    Speed Grade 7 is speed of FPGA logic
