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. 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).

APPLICATIONS
The Marvell Alaska Quad GbE transceivers provide higher port count Gigabit switches, up to 48 ports, offering the industryÕs
highest integration and lowest power dissipation. Through integrated SERDES technology, the devices also offer optional support
for 1000BASE-SX/LX Gigabit fiber standards, on a per port basis, enabling mixed-media Gigabit switches. These devices support
five different PHY/MAC interface options: GMII, RGMII, SGMII, TBI, and RTBI.
