Alaska® Octal
Gigabit Ethernet Transceiver
88E1180
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
Octal (88E1180) transceiver is the industryÕs Þrst and only 8-port GbE transceiver and offers the lowest power
dissipation at only 0.75 W/port. 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 Octal device offers additional support of 1000BASE-X
through an integrated 1.25 GHz Serializer/Deserializer (SERDES).

APPLICATIONS
The Marvell Alaska Octal GbE transceiver enables higher port count Gigabit switches, up to 48 ports and beyond, offering the industryÕs highest integration and lowest power dissipation. Through integrated SERDES technology, the device also offers
optional support for 1000BASE-SX/LX Gigabit Þber standards, on a per port basis, enabling mixed-media Gigabit switches. The device supports the RGMII, SGMII and RTBI PHY/MAC interface options.
The Alaska Octal transceiver combined with the Marvell Presteraª Gigabit Ethernet switches provide systems manufacturers with a complete networking solution from the PHY to the switch fabric, and allow for the development of high port count Gigabit
Ethernet switches with the fewest number of devices possible. For example, a 24-port Gigabit Ethernet switch can now be
comprised of just Þve Marvell chips (three Alaska Octal PHYs and two Prestera-EX switches)Ñless than half the number of components previously required.
