T2M Ethernet Ethernet 40G PCS IP

Ethernet 40G PCS IP

Description and Features

Ethernet 40G PCS core is compliant with IEEE Standard 802.3.2018 Ethernet specification. Through its Ethernet compatibility, it provides a simple interface to a wide range of low-cost devices. Ethernet 40G PCS IP is proven in FPGA environment. It can also supports a variety of host bus interfaces for easy adoption into any design architecture - AHB, AHB-Lite, APB, AXI, AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or custom buses.
