Alaska Gigabit Ethernet PHYs Transceivers Marvell Alaska® Gigabit Ethernet PHYs Transceivers are Physical Layer (PHY) Devices integrating 1000BASE-T, 100BASE-TX, and 10BASE-T standards. The Alaska Gigabit Ethernet PHYs Transceivers are designed for industrial applications where low and deterministic latency through the PHY enables real-time applications. Higher layer protocols such as EtherCAT/Profinet can utilize this low latency device to guarantee the quality of service in real-time automation systems. The efficient design of the Marvell Alaska Gigabit Ethernet Transceivers enables increased density, reduced power, and smaller package size.
