1. Agilex™ 7 F-Series and I-Series LVDS SERDES Overview

Updated for:
Intel® Quartus® Prime Design Suite 24.2
The Agilex™ 7 F-Series and I-Series I/O system includes three types of I/O interfaces: general purpose I/Os (GPIO), Secure Device Manager (SDM) I/O, and Hard Processor System (HPS) I/O. Each I/O interface caters to different interfacing requirements.

F-Series and I-Series devices support LVDS serializer/deserializer (SERDES) through the True Differential Signaling I/Os in the GPIO banks. The true differential I/Os are capable of supporting LVDS interfaces, including subsets such as:

  • RSDS
  • Mini-LVDS
  • Any I/O standards using equivalent electrical specifications

F-Series and I-Series devices support SERDES on all True Differential Signaling GPIO banks with the following features:

  • SERDES interfaces up to 1.6 Gbps.
  • Differential 100-ohm OCT RD.
  • Differential I/O reference clock for the I/O PLL that drives the SERDES.
  • Dedicated transmitter and dedicated receiver differential pin pairs in each I/O bank with multiple usage modes options.
  • In each I/O bank, there are 24 receiver channels with SERDES and DPA, and 24 transmitter channels with SERDES. The total number of SERDES channels varies across F-Series and I-Series devices, depending on the total number of pins available in the package.
