10G/25G Ethernet MAC


Comcores 10G/25G Ethernet MAC provides a complete IEEE 802.3 Ethernet Layer 2 solution. The MAC IP 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 can optionally include features like IEEE1588 and DMA integrations. The core is prepared for easy interfacing with Comcores 10G/25G PCS solution.

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.
