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.

PTP profiles for 5G networks

Niklas Meyer Mortensen Jan 04 2022 The IEEE 1588 PTP standards provide a wealth of options and the basis for highly reliable and accurate time synchronization solutions. However, the time synchronization needs of specific applications in different industries can vary quite significantly. These specific needs are defined in separate PTP profile standards, often in collaboration with other industry standards organizations. For 5G, both IEEE and ITU-T provide relevant profiles that can be used to...
