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 IEEE1588 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.
