Alaska® Quad
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).

APPLICATIONS
The Marvell Alaska Quad transceivers enable higher port count Gigabit switches, up to 48 ports. 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 Alaska Quad products support the GMII, RGMII, SGMII, TBI, and RTBI PHY/MAC interface options.
The Alaska Quad transceivers offer the most advanced feature set including VCT technology used to diagnose the attached cable
plant and isolate and report cable faults with one-meter accuracy. Additionally, the devices feature Ò2-pair downshiftÓ capability
for plug-and-play operation in 2-pair cable environments, as well the Media Detect feature which supports both copper and Þber
media simultaneously.
