The Agilex 7 FPGA F-Tile incorporates a fracturable, configurable, hardened Ethernet protocol stack for supporting rates from 10G to 400G, compatible with the IEEE 802.3 specification and other related Ethernet Consortium specifications. This intellectual property (IP) core implements Ethernet at data rates of 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, 200 Gbps and 400 Gbps. It is available in multiple variants providing different combinations of Ethernet channels and features. These include optional Reed-Solomon Forward Error Correction (RSFEC) and optional IEEE 1588v2 Precision Time Protocol (PTP). The user can choose a media access control (MAC) and a physical coding sublayer (PCS) variation, a PCS-only variation, a Flexible Ethernet (FlexE) variation, or an Optical Transport Network (OTN) variation. This IP core is included in the IP library and is available from the IP Catalog.
