The following figure shows a typical application for the core meeting the 1000BASE-X or 2500BASE-X standard using a device-specific transceiver to provide the Physical Coding Sublayer (PCS) and Physical Medium Attachment (PMA) sublayers for 1/2.5 Gigabit Ethernet.
- The PMA is connected to an external off-the-shelf Gigabit Interface Converter (GBIC) or Small Form-Factor Pluggable (SFP) optical transceiver to complete the Ethernet port.
- The GMII of the Ethernet 1000BASE-X or 2500BASE-X PCS/PMA is connected to an embedded Ethernet Media Access Controller (MAC), for example, the AMD Tri-Mode Ethernet MAC core in all supported devices or Ethernet MAC (EMAC0 or EMAC1) present in the AMD Zynq™ 7000 SoC or Gigabit Ethernet MAC (GEM0 or GEM1) present in Zynq AMD UltraScale+™ processing subsystem (PS) and AMD Versal™ CIPS. The core does not support 2500BASE-X and 2.5G SGMII when the core is generated to interface with the Ethernet MAC (EMAC0 or EMAC1) present in the AMD Zynq™ 7000 SoC or Gigabit Ethernet MAC present in Zynq AMD UltraScale+™ PS or AMD Versal™ CIPS.
