Comcores TSN MAC 10G/25G 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 10G/25G Ethernet Standard and is a low latency cut-through implementation, while keeping size at a minimum.
The core is fully configurable and interfaces easily to 10G/25G PCS, and can optionally include IEEE 1588 Timestamping Unit (TSU). The Ethernet MAC Core, on the Client side, implements a 64-bit AXI-S interface for Express and Preemptable traffic respectively while having a standard 64-bit XGMII interface on the PHY side.
