Due to a problem in Intel® Arria® 10 Core Fabric and General Purpose I/Os Handbook and Intel® Cyclone® 10 GX Core Fabric and General Purpose I/Os Handbook, Table 49 of Intel® Arria® 10 Programmable IOE Features I/O Buffer Types and I/O Standards Support, and Table 39 of Intel Cyclone 10 GX Programmable IOE Features I/O Standards and Buffer Types Support, don't include LVDS, RSDS, mini-LVDS and LVPECL I/O standards. These IO standards all support the I/O Delay feature.
This problem is currently scheduled to be fixed in a future release of Intel® Arria® 10 Core Fabric and General Purpose I/Os Handbook and Intel® Cyclone® 10 GX Core Fabric and General Purpose I/Os Handbook.
