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.

Alaska M Multi-gigabit Ethernet

The Alaska M family of 2.5G, 5G and 10G PHY devices is designed to enable enterprises to migrate to mGig Ethernet networking infrastructure quickly and cost-effectively. Alaska M PHY devices offer high performance, design simplicity and extremely low power dissipation, while supporting Category 5e, 6 and 6A type cables for distances up to 100 meters.

Compatible with the NBASE-T Alliance specification for 2.5G and 5G data rate over Cat 5e cables, Alaska M devices use DSP technology to enable the repurposing of low-cost CAT 5e Ethernet cables for data rates as high as 5 Gbps, supplanting the use of optical technology for applications such as Wi-Fi 5 and Wi-Fi 6/E access point backhaul, switches, servers, workstations and high-end PCs.

The Alaska M 10G PHY devices enable broad-based market adoption of 10 GbE network connectivity over Cat 6A cabling, supporting the roll-out of Wi-Fi 7 and networking infrastructure modernization. Alaska M 10G devices boast the industry’s lowest power, highest performance and smallest form factor in their category and integrate features such as Energy Efficient Ethernet (EEE), PTP/1588v2, SyncE, MACsec, and support for all PoE standards up to 100W.

• Multi-rate connectivity: 10 Gbps / 5 Gbps / 2.5 Gbps / 1 Gbps /100 Mbps
• Wi-Fi 5 (802.11ac), Wi-Fi-6/E (802.11ax) and Wi-Fi 7 (802.11be) access point backhaul
• Compliant with NBASE-T Alliance specifications for 2.5G and 5G modes
• Superior EMI mitigation: Fast Retrain and Common Mode Sense
• Auto Media Detect allows one device to act as an Optical (SFI) or Base-T PHY
• 10Base-T legacy support
• Energy Efficient Ethernet (EEE)
• Marvell Virtual Cable Tester® (VCT) technology
