Marvell Alaska V 88E1680
Eight port 10/100/1000Mbps Energy Efficient Ethernet (EEE) Transceiver
PRODUCT OVERVIEW
The Marvell® Alaska® V 88E1680 is a highly-integrated, ultra-low power eight-port 10/100/1000Mbps transceiver that supports
Energy Efficient Ethernet (EEE) compliant to IEEE 802.3az. Alaska V 88E1680 is a new class of gigabit ethernet transceivers that
incorporate innovative mixed-signal design to offer industry’s highest performance, lowest power in a thermally efficient and
space-saving package. In addition to supporting EEE with the new generation of MACs, 88E1680 is capable of implementing EEE
with legacy or non-EEE MAC devices. This accelerates time-to-market for customers offering EEE complaint networking solutions
to leverage existing hardware and software while saving development costs. In addition, 88E1680 offers unprecedented cable-
length performance allowing customers to deploy across a wide-base of cabling infrastructure.
The Alaska V 88E1680 supports QSGMII (Quad-SGMII) MAC interface running at 5Gbps data-rate thus lowering pin-count, package
costs, and reducing overall power consumption. This greatly complements Marvell’s Prestera® DX family of high-density switches
offering a highly efficient and cost-effective EEE compliant solutions.
