Ethernet 400G MAC
Design IP
Overview

SmartDV’s Ethernet 400G MAC IP Core delivers ultra-high-speed connectivity designed for next-generation data centers, cloud infrastructure, AI/ML platforms, and high-performance networking environments. Compliant with IEEE 802.3bs and 802.3ck standards, it supports 400 Gigabit Ethernet operation with robust features that ensure high throughput, low latency, and reliable data transfer.

The IP core includes support for full-duplex operation, jumbo frames, frame filtering, VLAN tagging, priority-based flow control (PFC), checksum generation and verification, and statistics counters. It offers seamless interoperability with 400G PCS and PHY layers through standard interfaces like CDMII and CGMII.

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. Its advanced architecture is ideal for building scalable, high-bandwidth networking systems that demand deterministic performance and superior data integrity.
