Tri-Mode Ethernet Media Access Controller (TEMAC)


Product Description

The TEMAC core is ideally suited for the development of high density Gigabit Ethernet communications and storage equipment.

The AMD Tri-Mode Ethernet MAC core is a parameterizable core ideally suited for use in networking equipment such as switches and routers. The customizable TEMAC core enables system designers to implement a broad range of integrated Ethernet designs, from low cost 10/100/1000 Mbps Ethernet to higher performance 2.5 Gigabit ports. The TEMAC core is designed to the IEEE 802.3 specification and operates in 2500 Mbps, 1000Mbps, 100 Mbps, and 10 Mbps modes. In 1000/2500Mbps mode, the TEMAC connects to the AMD 1/G2.5G PCS/PMA. In 1000 Mbps mode, the TEMAC core can also connect with industry standard PHY devices. In 10/100 Mbps mode, the TEMAC uses the MII interface. The AMD Tri-Mode Ethernet MAC, combined with the Ethernet 1G/2.5G PCS/PMA or SGMII core, provides a complete and highly flexible solution for the implementation of Ethernet Link and Physical layers and is available as a single IP through AXI 1G/2.5G Ethernet. The TEMAC core is delivered through Vivado™ Design Suite and is part of the comprehensive suite of AMD Ethernet solutions.
