Broadcom Introduces Full Featured, Lowest-Power Multi-port Gigabit PHYs
Broadcom today announced a new generation of energy efficient devices for its enterprise and carrier class PHY portfolio. Optimized for use in power-intensive Ethernet network applications, the 40 nanometer BCM54290 family of physical layer transceivers 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 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 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.
