Low power Gb Ethernet physical layer devices from Vitesse

Vitesse Semiconductor Corporation has expanded of its energy-efficient SimpliPHY family of Gigabit Ethernet (GE) physical layer devices. Vitesse says with green features that reduce power consumption by 75 percent or more, the VSC8552 and VSC8504 are ideal for products such as broadband access gateways, Enterprise IP phones, switches, routers, and smart grid connectivity devices.

The key features and benefits include:

The two-port VSC8552 and four-port VSC8504 devices support dual media copper and fiber ports
Power dissipation between 160mW and 400 mW per port depending upon traffic utilization levels for an active link over twisted-pair copper wiring.

The technology used is compliant to the Energy Star framework with features such as PerfectReach, an intelligent cable length algorithm that saves power based on the reach of a connection and ActiPHY(Vitesse claims reduces power consumption by 75 percent or more for unconnected ports).

Delivers high-energy efficiency features with LED brightness control and unique integrated temperature-monitoring and fan-control logic.

Can utilize the VSC8552 in an RGMII-to-SGMII conversion mode for a low-power solution. Similarly, the VSC8504 can perform SGMII-to-QSGMII conversion.

"Network equipment vendors across all segments are looking for ways to reduce system power and increase system efficiency," said Dinesh Kannappan, product marketing manager at Vitesse. "Vitesse is committed to remaining at the forefront in green innovations, which helps our customers gain a competitive edge and bring differentiated energy-efficient network solutions to market."

Samples of the lead-free RoHS 6 devices, in 17-mm-square 256-pin BGA packages, are available immediately, with production scheduled for July 2011.
