1. Intel Agilex General-Purpose I/O Overview

Updated for:
Intel® Quartus® Prime Design Suite 22.1
The Intel® Agilex™ I/O system includes three types of I/O interfaces. Each I/O interface caters to different interfacing requirements.
Table 1.  Types of I/O Interfaces
Interface Type Features
General-purpose I/O (GPIO)
  • 1.2 V single-ended non-voltage referenced JEDEC compliant I/O standards.
  • 1.2 V single-ended and differential voltage referenced JEDEC compliant I/O standards.
  • True differential I/O compatible with LVDS, capable to interface with LVDS subsets such as:
    • RSDS
    • Mini-LVDS
    • Any I/O standards using equivalent electrical specifications
  • DDR4 memory interface up to 1,600 MHz with a Hard Memory Controller (HMC).
  • LVDS serializer/deserializer (SERDES) interface up to 1.6 Gbps.
