Ethernet MAC

General Description

Comcores’s 10G TSN MAC 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 application like Radio Over Ethernet and Automotive. The MAC-core performs the Link function of the 10Gb 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 is prepared for IEEE1588 integration and easy interfacing to Comcores 10G PCS. The Ethernet MAC Core, on the Client side, implements two 32-bit or 64-bit asynchronous FIFO interfaces for Express and Preemptable traffic respectively while having a standard XGMII interface on the PHY side.
