The AMD Ethernet Quad Serial Gigabit Media Independent Interface PCS/PMA or QSGMII IP LogiCORE™ IP provides an Ethernet Physical Coding Sublayer (PCS) with an aggregation of four 10/100/1000M ports to one five gigabit transceiver. QSGMII interfaces are implemented using transceivers in Virtex™ 7 or Kintex™ 7 devices. On the front end, the LogiCORE IP can also interface seamlessly to four Ethernet MACs through a built-in Gigabit Media Independent Interface (GMII). This IP is available through CORE Generator™ software at no charge to help you accelerate your time to market. It is built upon our existing Serial Gigabit Media Independent Interface PCS/PMA IP.
