APPLICATIONS
The Marvell Alaska Quad transceivers enable higher port count Gigabit switches, up to 48 ports. Through integrated
SERDES technology, the device also offers optional support for 1000BASE-SX/LX Gigabit Þber standards, on a per port
basis, enabling mixed-media Gigabit switches. The Alaska Quad products support the GMII, RGMII, SGMII, TBI, and RTBI
PHY/MAC interface options.
The Alaska Quad transceivers offer the most advanced feature set including VCT technology used to diagnose the attached cable
plant and isolate and report cable faults with one-meter accuracy. Additionally, the devices feature Ò2-pair downshiftÓ capability
for plug-and-play operation in 2-pair cable environments, as well the Media Detect feature which
supports both copper and Þber media simultaneously.
