Ethernet TSN MAC 10M/100M/1G/2.5G

Overview

Comcores TSN MAC 10M/100M/1G/2.5G provides a complete IEEE 802.3 Ethernet Layer 2 solution with support for key TSN features including 802.1Qbu Preemption, 802.3br Interspersing Express Traffic, and optionally 802.1AS Timing and Synchronization and 802.1Qbv Enhancements for Scheduled Traffic.

The TSN MAC enables deterministic low latency and guaranteed jitter for time sensitive applications. The TSN MAC allows flexibility in selecting a subset of standards depending on your application from industrial to automotive.

The feature rich MAC core is a low latency cut-through implementation, while keeping size at a minimum. The core is fully configurable and can optionally include IEEE 1588 Timestamping Unit (TSU). The Ethernet MAC Core has a standard GMII interface on the PHY side, with MII and RGMII being optional.

What is TSN?

Morten Kofoed Esbjørn - Feb 14, 2023. TSN, or Time-Sensitive Networking, is a technology based on the IEEE 802.1Q standard. It has evolved from the Ethernet technology currently used to carry all types of traffic, for which ethernet was not originally intended, such as multiple data flows with different timing requirements, commonly found in Audio Video Bridging (AVB), automotive and industrial automation applications. TSN sits in Layer 2 of the OSI Model (figure 1).Figure 1: Illustration of...
