LVDS pin detail on Arria 10

Hi,

Check this https://www.intel.com/content/www/us/en/docs/programmable/683461/current/i-o-and-differential-i-o-buffers-in-devices.html

LVDS I/O bank—supports differential and single-ended I/O standards up to 1.8 V. So you can use for single-ended.

If that IO you're using for LVDS SERDES, I don't think you can use 1.8V check this SERDES I/O Standards Support in Arria® 10 Devices https://www.intel.com/content/www/us/en/docs/programmable/683461/current/serdes-i-o-standards-support-in-devices.html

Thanks,

Regards,

Sheng
