Ethernet 40G MAC
Design IP
Overview

SmartDV’s Ethernet 40G MAC IP Core is a robust, high-throughput solution designed to meet the performance needs of data centers, cloud infrastructure, enterprise networking, and storage systems. Supporting IEEE 802.3ba standard, it enables reliable full-duplex 40 Gigabit Ethernet communication with advanced features for efficient data handling.

The IP core supports functions such as frame filtering, CRC generation and checking, VLAN tagging, jumbo frame support, and statistics counters. Optional features like Energy Efficient Ethernet (EEE), flow control, and preemption enhance system-level efficiency and flexibility.

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. With seamless integration into Ethernet subsystems via standard PHY interfaces like XLGMII, the 40G MAC IP is well-suited for bandwidth-intensive applications that demand low latency and high data integrity.
