Ethernet TSN MAC 40G/100G

Overview

Comcores TSN MAC 40G/100G provides a complete IEEE 802.3 Ethernet Layer 2 solution with support for key TSN features including 802.1Qbu Preemption and 802.3br Interspersing Express Traffic. This enables the use of the MAC in high speed time-critical applications.
The MAC-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 fully configurable, interfaces easily to standard 40G/100G PCS due to its CGMII interface, and can optionally include IEEE 1588 Timestamping Unit (TSU).
The Ethernet MAC Core, on the Client side, implements a 256-bit AXI-S interface for Express and Preemptable traffic respectively 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...
