1. About the Low Latency E-Tile 40G Ethernet Intel FPGA IP

Updated for:
Intel® Quartus® Prime Design Suite 21.2
IP Version 21.0.0

The Low Latency E-Tile 40-Gbps Ethernet (LL E-Tile 40GbE) IP core is used in multiple variants of the Intel® Stratix® 10 and Intel® Agilex™ device families. The IP core implements the IEEE 802.3-2010 40G Ethernet Standard and includes options to support unidirectional transport as defined in Clause 66 of the IEEE 802.3-2012 Ethernet Standard.

The MAC client side interface for the Low Latency E-Tile 40G Ethernet IP core is a 128-bit Avalon® streaming interface and a 32-bit Avalon® memory-mapped interface control path. The network interfaces are standard XLAUI interfaces.

The IP core provides standard media access control (MAC), physical coding sublayer (PCS), and physical medium attachment (PMA) functions.
