These products are commercially available transceivers that cover applications at 10G, 1G and 100Mb Ethernet speeds. The Alaska 88X2140M quad-port and 88X2120M dual-port series of 10G transceivers feature XFI 10G serial and reduced XAUI interfaces to support SFP+ applications.
These 10G PHYs are for dense multi-port applications such as carrier class switches and routers. The Alaska 88E1542M and 88E1522M products are designed to support 1000BASE-X and 100BASE-FX in quad-port and dual-port configurations in space-efficient, cost-optimized packages enabling high port-densities as well as modular applications.
These products incorporate Marvell's second generation LinkCrypt technology, which merges MAC layer security functions in the Ethernet physical layer to enable secure converged networks delivering voice, video, and data capabilities.
