Broadcom has developed a new generation of energy efficient PHY devices for power-intensive Ethernet network applications.
The 40nm BCM54290 family of physical layer transceivers
(PHYs) delivers the industry's lowest power consumption and offers a 40
percent power reduction compared to previous generation 65nm GPHYs.
High data volume and the need for greater processing power lead to a
significant increase in power consumption across the network. Broadcom's
Energy Efficient Ethernet (EEE) portfolio with AutoGrEEEn Plus
technology delivers up to 70 percent lower power consumption and extends
energy savings to legacy MACs and non-EEE devices. The technology can
be deployed when the device is in Energy Efficient Ethernet (EEE) mode
communicating with an EEE link partner or when linked to a non-EEE
"Highly precise synchronization, accurate latency management and power consumption are critical considerations for carrier Ethernet
networks as they prepare for 4G deployment. The BCM54290 PHY family is
tailor-made for use in stringent time synchronization applications and
designed to address the challenges faced by LTE and LTE-Advanced
networks," said Dr. Ali Abaye , Broadcom Senior Director of Product
The BCM54290 family includes octal and quad port devices with
copper/fiber dual media interface variants. The devices are fully
compliant to EEE for 1000BASE-T and 100BASE-TX as defined by the IEEE
Std 802.3-2012 standard, supporting Synchronous Ethernet, 1588 precision
time synchronization with 1ns time stamping and Y.1731 latency
performance monitoring as well as SyncE+ and IEEE 802.3bf support and
cable plant diagnostics that detect cable plant impairments.
The BCM54290 PHY is now sampling with production volume slated for 1H14.
