Agilex F tile the FGT Xcievers REFCLK

Hi, We use on the Agilex F tile the FGT Xcievers with AC coupling. Intel Agilex datasheet below requires differential p-p voltage of 1.2V. please see attachment . In the eval board we saw th...

Hi,


From what I understand, voltage swing is specified as single-ended mVpp while in the Agilex Datasheet it shows the Vdiff AC as Vpp-diff.


Vpp_diff = 2*Vpp_se


So, based on the LVDS in the Silicon labs datasheet, it shows 430mVpp_se typ. If we calculated according to the formula above, we got 860mVpp-diff which are still in the range of specification stated in Agilex datasheet.


Regards,
