1. E-Tile Transceiver PHY Overview

The E-tile is a 24-channel, PAM4/NRZ dual-mode transceiver tile that is used in multiple variants of the Intel® Stratix® 10 and Intel® Agilex™ device families. Refer to the respective Product Tables and Pin-Out Files for Intel® FPGA Devices to find the actual number of transceivers available in each device.

Below is the performance comparison of E-tile to L-tile and H-tile transceiver tiles.
