Gigabit Ethernet Transceiver

88E1141/88E1145

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

Quad 88E1141 and 88E1145 transceivers lead the industry with the lowest power consumption (under 3W for the

entire device), enabling network systems manufacturers to decrease system cost by reducing both power supply

and fan requirements. Additionally, the 88E1145 device offers the smallest package footprint (21 mm x 21 mm)

and requires 40% less board space than competing Gigabit solutions. The Alaska Quad products offer additional

support of 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).
