Transceiver Solutions
Alaska(R) Quad
Gigabit Ethernet Transceiver
88E1141/88E1145
PRODUCT OVERVIEW
The Marvell Alaska family of Gigabit Ethernet (GbE) over copper transceivers are the industryOs 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).

BENEFITS
Automatically congures to 10, 100 or 1000 Mbps Lower cost magnetics Eliminates cost of external LED latches and drivers User-dened LED conguration Works with all existing Gigabit switch designs Assists testing and diagnostics
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 ber 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 O2-pair downshiftO capability for plug-and-play operation in 2-pair cable environments, as well the Media Detect feature which supports both copper and ber media simultaneously.
