Broadcom unveils energy efficient physical layer transceivers

Telecom Lead America: Broadcom Corporation has
expanded its Energy Efficient Ethernet (EEE) portfolio with the launch of four
energy efficient devices known as 10/100/1000BASE-T physical layer transceivers
(PHYs).

 

All devices are now sampling with production volume
slated for the second half of 2012.

 

Optimized for use in power-intensive Ethernet network
applications, these physical layer transceivers (PHYs) lower operating power by
more than 40 percent, and up to 70 percent or more through the implementation
of EEE.

 

“Network operators of all types can benefit from
lower power consumption, which reduces energy costs and lowers overall
operating costs for IT organizations. Broadcom is a leader in the
innovation and delivery of products that dramatically reduce power consumption
while increasing bandwidth. Our latest PHYs are an extension of that
leadership, and provide IT professionals with an easy and effective way to
maximize the benefits of EEE technology,” said Kevin Brown, vice president and
general manager, PHY at Broadcom.

 

The BCM54240, BCM54280, BCM54282 and BCM54285 implement
the IEEE 802.3 EEE standard directly into the physical layer, while Broadcom’s
AutoGrEEEn technology enables systems with legacy MACs to leverage the power
savings of EEE in periods of low link utilization, thus reducing
time-to-market.

 

In addition to reducing power consumption and energy
costs, the new PHYs provide integrated on chip 1588 PTP and Y.1731 delay
measurement to deliver the most complete set of features in their class for
timing synchronization and latency measurement .

 

More than 150 million metric tons of carbon dioxide (CO2)
is used to power IT equipment with a global price tag of approximately $16
billion per year. The company said that increasing pressure on network
managers to adopt and implement more energy efficient technologies will drive
the demand of such energy efficient PHYs.

 

Broadcom launches two 10GBASE-T physical layer transceivers

 

Recently, Broadcom Corporation launched two 10GBASE-T
physical layer transceivers (PHYs).

 

Adding to its growing portfolio of 10GBASE-T networking
solutions, the integrated quad-port BCM84844 and dual-port BCM84846 lower
operating power by more than 50 percent.
