Ethernet TSN MAC 10G/25G


Comcores Ethernet 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 reaching best in market results while still keeping size at a minimum. The core is fully configurable and interfaces easily to 10G/25G PCS. Features like IEEE1588 solution, VLAN and DMA integration can optionally be included.

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 XGMII interface on the PHY side.
