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


Comcores 10M/100M/1G/2.5G Ethernet MAC IP solution is a low latency and low size solution that complies to IEEE 802.3 while keeping implementation complexity 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 10/100/1000/2500 SGMII PCS IP solution. The structure agnostic implementation ensures easy use and integration whether the target technology is FPGA, ASSP or ASIC.
