Ethernet 1G/2.5G BASE-X PCS/PMA or SGMII


Product Description

The Ethernet 1G/2.5G PCS/PMA or SGMII IP LogiCORE™ provides an Ethernet Physical Coding Sublayer (PCS) with a choice of either a 1G/2.5G BASE-X Physical Medium Attachment (PMA) or Serial Gigabit Media Independent Interface(SGMII). 2.5GBASE-X and 2.5G SGMII is available in Versal™ adaptive SoC, Kintex™ UltraScale+™, Virtex™ UltraScale+, Zynq™ UltraScale+, Kintex UltraScale, Virtex UltraScale™, Virtex 7 and Kintex 7. 1000BASE-X and SGMII interfaces are implemented using transceivers in Virtex 7, Kintex 7, Artix 7, Zynq 7000, Virtex 6, Virtex 5, Virtex 4 FX, Virtex II Pro and Spartan™ 6 or using Select I/O and the parallel Ten-Bit interface(TBI) interface  in Virtex 7, Kintex 7, Virtex 6, Virtex 5, Virtex 4, Virtex II Pro, Virtex II, Spartan 6, Spartan 3, Spartan 3A / 3AN, Spartan 3A DSP and Spartan 3E families. AMD supports 1000BASE-X/SGMII over Select I/O. On the front end, the IP LogiCORE can also interface seamlessly to an Ethernet MAC through a built-in Gigabit Media Independent Interface (GMII).
