Fast & Gigabit Ethernet

Marvell offers a comprehensive portfolio of Alaska® Fast Ethernet and Gigabit Ethernet PHY transceivers to address various Ethernet networking standards. These PHYs are built on Marvell’s legacy of providing unique, best-in-class features that enable customers to expand their Ethernet applications. With efficient design and a high-level of integration, Marvell’s PHYs bring low power dissipation, small form factor, high performance and advanced feature sets.

Marvell’s Gigabit Ethernet PHYs allow thermal-efficient packages for fan-less, heat-sink-less designs while the octal members of the Fast Ethernet PHY family lead the industry with the lowest power consumption, resulting in reduced fan requirements. Both PHY families feature Marvell’s Virtual Cable Tester® (VCT) technology, allowing IT managers and networking equipment manufacturers to analyze quickly and remotely the quality and attributes of the cable, avoiding unnecessary equipment returns and on-site service calls.
