Broadcom Intros Four Energy Efficient Ethernet (EEE) PHYs

Broadcom has added four energy efficient chips to its Energy Efficient Ethernet (EEE) portfolio.


The new 10/100/1000BASE-T physical layer transceivers (PHYs) lower operating power by more than 40 percent, and up to 70 percent or more through the implementation of EEE directly at the physical layer. The PHYs also feature Broadcom's AutoGrEEEn technology, which enables systems with legacy MACs to leverage the power savings of EEE in periods of low link utilization. This allows customers to transform existing network equipment to EEE-compliance simply by changing the PHY device.

In addition to reducing power consumption and energy costs, Broadcom said its new PHYs provide integrated on chip 1588 PTP and Y.1731 delay measurement for timing synchronization and latency measurement — critical features for service provider and industrial Ethernet applications.

All devices are now sampling with production volume slated for the second half of 2012. http://www.broadcom.com
