OVERVIEW
The Alaska® Ultra 88E1111 Gigabit Ethernet Trans ceiver is a physical layer device for Ethernet 1000BASE-T, 100BASE-TX, and 10BASE-T applications. It is manufactured using standard digital CMOS
process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on standard CAT 5 unshielded twisted pair.
