Hi Aqid,

Thanks for your reply.

I saw it on the Agillex eval board . its driven with LVDS (at least the note says) with 350mV Swing. (please see previous attachments and attached sheet 38) ,

however the Intel datasheet requires Vrefin diff-AC of 1.2V . please see previous attachments .

I am attaching the evaluation board schematic of the Agillex F- Tile.

please look at sheet 38 for example : REFCLK_156M_QSFPDD_P ,N output of the Silicon labs clock driver.

Thanks
