Marvell Alaska V 88E1680
Eight port 10/100/1000Mbps Energy Efficient Ethernet (EEE) Transceiver
APPLICATIONS
The Alaska V 88E1680 enables a wide range of applications in spanning SMB to enterprise, metro ethernet and
wireless backhaul. 88E1680 is a key component of Marvell’s cloud-infrastructure solutions enabling deployment of
EEE-compliant public and private cloud systems. The time-aware features offered in 88E1680 - synchronous ethernet,
and IEEE1588v2 - are essential in metro ethernet, industrial ethernet and wireless backhaul.
PRODUCT OVERVIEW
Marvell
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
family of high-density switches offering a highly efficient and cost-effective EEE compliant solutions.
