Alaska F and Alaska G
Fast and Gigabit Ethernet

The Alaska® F and Alaska G families of Fast Ethernet and Gigabit Ethernet physical layer (PHY) transceivers are built on Marvell’s legacy of unique, best-in-class features that enable customers to expand their Ethernet applications. With efficient design and a high level of integration, Alaska F and Alaska G PHY devices offer low power dissipation, small form factors, high performance and advanced feature sets.

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