Ethernet 25G MAC
Design IP
Overview

SmartDV’s Ethernet 25G MAC IP Core is a high-performance solution developed for data-intensive applications across networking equipment, enterprise systems, and data center infrastructure. Supporting IEEE 802.3by, the IP core delivers 25 Gbps full-duplex Ethernet connectivity with robust flow control, frame handling, and error detection features.

It includes support for jumbo frames, VLAN tagging, pause frame generation, and checksum offloading, providing the necessary flexibility and performance for next-generation Ethernet systems. The MAC IP can interface seamlessly with PCS layers and standard PHY interfaces such as XGMII and USXGMII.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance.
