APPLICATIONS
The Marvell Alaska Quad GbE transceivers provide higher port count Gigabit switches, up to 48 ports, offering the industryÕs
highest integration and lowest power dissipation. Through integrated SERDES technology, the devices also offer optional support
for 1000BASE-SX/LX Gigabit fiber standards, on a per port basis, enabling mixed-media Gigabit switches. These devices support
five different PHY/MAC interface options: GMII, RGMII, SGMII, TBI, and RTBI.
