Broadcom's Next Gen 40nm PHYs Promise 40% Power Savings


Broadcom introduced a new generation of 40 nanometer (nm) enterprise and carrier class PHY devices that offer a 40 percent power reduction compared to previous generation 65nm GPHYs.

The new devices are fully compliant to EEE for 1000BASE-T and 100BASE-TX as defined by the IEEE Std 802.3-2012 standard. Key features include support for Synchronous Ethernet, 1588 precision time synchronization, Y.1731 latency performance monitoring, 1ns 1588 PTP time stamp resolution, and enhanced cable plant diagnostics that detect cable plant impairments.

The BCM54290 40nm multi-port Gigabit PHY family consists of the following six device options:

  • BCM54290: Octal-port SGMII 10/100/1000BASE-T PHY
  • BCM54292: Octal-port QSGMII 10/100/1000BASE-T PHY
  • BCM54295: Octal-port QSGMII 10/100/1000BASE-T PHY with copper/fiber dual media interface
  • BCM54294: Quad-port SGMII 10/100/1000BASE-T PHY with copper/fiber dual media interface
  • BCM54291: Quad-port QSGMII 10/100/1000BASE-T PHY
  • BCM54296: Quad-port QSGMII 10/100/1000BASE-T PHY with copper/fiber dual media interface

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 enabled device.

"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 Marketing, PHY. "Enabling system OEMs and service providers to meet increasing traffic demands, Broadcom's new generation of PHY products enhance both power efficiency and performance."

The BCM54290 PHY is now sampling with production volume slated for 1H14.
