6.2. The Intel Agilex® Platform

The card design for the Intel® Arria® 10 and Intel® Stratix® 10 families works on a typical level shifters from 1.8 V up to 3.3 V. However, to support future platform families and to extend the time frame for portability, Intel recommends a daughtercard level shifter of 1.0 V for general purpose (GPIO).

Intel recommends a card design that includes DDC lines with proper pullup termination; the signals require mitigating voltage drop along the compliant cables.
