88E1112-C2-NNC1I000

The Alaska® 88E1112 Gigabit Ethernet Transceiver  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.

The Alaska 88E1112 device supports the Serial Gigabit Media Independent Interface (SGMII) for direct connection to a MAC/Switch port. The 88E1112 device incorporates an additional 1.25 GHz SERDES (Serializer/Deserializer) which may be connected directly to a fiber-optic transceiver for 1000BASE-X applications. The SERDES is switchable to support 125 MHz operation for 100BASEFX applications. Additionally, the 88E1112 device may be used to implement 10/100/1000BASE-T Gigabit Interface Converter (GBIC) or Small Form Factor Pluggable (SFP) modules.

The 88E1112 device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a gigabit per second data rate. The device achieves robust performance in noisy environments with very low power dissipation.
