Ethernet MAC 40G/100G

Overview

Comcores Ethernet MAC 40G/100G provides a complete IEEE 802.3 Ethernet Layer 2 solution. The MAC IP core performs the Link function of the 40G/100G Ethernet Standard and is a low latency cut-through implementation, while keeping size at a minimum.

The core is highly configurable and easy interfacing with Comcores IEEE 1588 Timestamping Unit (TSU) and 40G/100G PCS solutions.
The Ethernet MAC Core, on the Client side, implements a 256-bit AXI-S Client interface while having a standard 256-bit CGMII interface on the PHY side.

MACsec for Deterministic Ethernet applications

WHITEPAPER MACsec provides authentication by ensuring that only known nodes are allowed to communicate on the LAN. It provides confidentiality through encryption of the data so only end-points with the correct encryption key can see the contents. Integrity is provided through mechanisms that can detect any interference with data in motion. MACsec operates at the data link layer acting as a client of the Ethernet Media Access Control. While the ability of MACsec to scale to high speeds is...

Daniel Dik Sep 14 2022 5G provides a range of improvements compared to existing 4G LTE mobile networks in regards to capacity, speed, latency and security. One of the main improvements is in the 5G RAN; it is based on a virtualized architecture where functions can be centralized close to the 5G core for economy or distributed as close to the edge as possible for lower latency performance. The functional split options for the baseband station processing chain results in a separation between...
