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

Overview

Product Description

The Xilinx 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 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. Xilinx 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).
