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 Ultra single-channel GbE transceivers, consisting of the 88E1011 and 88E1011S devices, are the industryÕs first GbE PHYs optimized for the mobile computing market. These devices perform all of the physical layer functions for 100BASE- TX and 1000BASE-T full or half duplex Ethernet on category 5 (CAT 5) twisted pair cable, and 10BASE-T full or half duplex Ethernet on CAT 3, 4 and 5 cable. The Alaska Ultra+ device (88E1011S) offers additional support of 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).
