PRODUCT OVERVIEW
The Marvell

Alaska
簍
family of Gigabit Ethernet (GbE) over copper transceivers are the industry脮s lowest power,
smallest form factor, highest performance, and highest port density solutions in volume production. Targeted
at high-density GbE switches, the Alaska Quad transceivers are single-chip devices containing four independent
GbE PHYs on a single monolithic IC. Each transceiver performs 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 Quad devices (88E1040S, 88E1041S and 88E1042H) offer
additional support of 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).
