Max 10 - Difference in performance between low-speed and high-speed I/O pins

Hi, Could someone please explain the difference in performance between the low-speed and high-speed Max 10 I/O pins? I have searched the datasheet and have not be able to readily find the differen...

I don't think that the old post is inaccurate. The quoted 310 versus 310 Mbps numbers are correctly quoted from the datasheet.

You probably miss the important point. It's so that so called "low-speed" pins don't support certain IO standards at all, e.g. no true LVDS. The speed difference for the supported IO standards is almost negligible.

Sorry I think you missed my point, that GooGooCluster misquoted and said that low-speed pins support data rates up to 300 Mbps... where in the documentation does it say that? I read through several times and it *exclusively* lists high-speed transmitting specifications.. making the assumption that the slowest max speed listed under the heading "High-Speed I/O Specifications" is the low-speed limit seems a bit too much of a stretch. No need to interpolate guys, stick to facts.
