Alaska® Single-Port
Gigabit Ethernet Transceiver
88E1111
PRODUCT OVERVIEW
The Marvell¨ Alaska¨ family of Gigabit Ethernet (GbE) over copper transceivers are the industryÕs lowest power,
smallest form factor, highest performance, and highest port density solutions in volume production. The Alaska
single-port 88E1111 transceiver leads the industry with the lowest power consumption (only 0.75W), as well as
the smallest package footprint option Ñ only 9 mm x 9 mm. The Alaska single-port 88E1111 product performs all
of the physical layer (PHY) functions for half- and full-duplex 10BASE-T Ethernet on CAT 3, 4 and 5 cable, and
half- and full-duplex 100BASE-TX and 1000BASE-T Ethernet on CAT 5 twisted pair cable. Additionally, the 88E1111
device offers additional support of 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).
