The RTL8218FB integrates octal independent Gigabit Ethernet transceivers into a single IC. The device performs all the physical layer (PHY) functions for 1000Base-T, 100Base-TX, and 10Base-T Ethernet on category 5 UTP cable except 1000Base-T half-duplex. 10Base-T functionality can also be achieved on standard category 3 or 4 cable.
The RTL8218FB Each of the two independent transceivers features an innovative RSGMII-Plus/QSGMII for reduced PCB traces. All transceivers can communicate with the MAC simultaneously through the same RSGMII-Plus/QSGMII.
