Quad PHY is cooler choice for switching

Quad gigabit Ethernet PHY chip cuts costs and power consumption in high-density switching applications.

Marvell has added the 88E1240 to its Alaska family of single, dual, quad and octal gigabit Ethernet (GbE) transceivers.

Featuring low power consumption, advanced power saving modes and a high-level of integration, the 88E1240 greatly reduces system costs and improves thermal efficiency in high-port density switching applications.

Marvell Alaska is a complete family of innovative Ethernet PHY transceivers that meet the unique configurations and requirements of today's vast networking environments.

The Alaska 88E1240 is Marvell's latest pin-compatible addition to the quad-PHY family.

The 88E1240 consumes less than 500mW per port in 1000Base-T full-duplex mode, significantly lowering the thermal profile of fanless systems.

The active low-power consumption of the 88E1240 combined with its advanced power-saving modes, delivers a new level of energy efficiency for a new breed of cost-optimised, entry-level GbE switching platforms built on Marvell's industry leading Prestera DX switch devices.

The 88E1240 integrates line-side terminations that greatly improve signal quality while reducing bill-of-material (BOM) costs and saving precious board space.

This integration of passives improves system-level reliability while lowering the manufacturing and overall system costs.

The 88E1240's pin compatibility with existing Marvell quad PHYs that are widely deployed in the market minimises operating expenses, design risk, and time to market for next-generation switch designs.

The 88E1240 also includes Marvell's VCT technology for advanced cable diagnostics.

"As an industry leader in the innovation and development of transceiver solutions, Marvell continually delivers the most advanced and complete portfolio of PHY products to the Ethernet switching market", says David Young, Vice President and General Manager, Connectivity Business Unit, Communications and Consumer Business Group at Marvell.

"The Alaska 88E1240 quad PHY sets a new industry standard for low power consumption while enabling ultra-efficient system design for the complete range of enterprise and SMB switching applications".

The 88E1240 is available in both BGA and TQFP packages and is currently sampling with tier-one customers.
