15 You must enable the PCI clamp diode.
16 Even though the Intel® Cyclone® 10 LP I/O buffers support various I/O standards for memory application, Intel does not validate nor support any IP that is intended for memory applications such as DDR or DDR2.
17 The inputs treat differential inputs as two single-ended inputs but decode only one of them.
18 The outputs uses two single-ended outputs with the second output programmed as inverted.
19 Emulated LVDS, mini-LVDS, RSDS, and PPDS I/O standards requires external resistors.
20 The inputs use LVDS input buffers.
