PRODUCT OVERVIEW
The Marvell
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 industrys 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).
