Broadcom 10GBASE-T PHYs deliver fifty percent lower power

Broadcom Corporation today announced the addition of two 10GBASE-T physical layer transceivers (PHYs) to its growing portfolio of 10GBASE-T networking solutions. Optimized for top-of-rack switches, 10GbE server adapters and LOMs (LAN on motherboard) in the data center, the highly integrated quad-port BCM84844 and dual-port BCM84846 lower operating power by more than 50 percent. The new PHYs reduce power consumption at 10GE to less than two watts per port through the use of EEE, and extend the benefits of EEE to include all device speeds including 1GbE. As a result of increasing network traffic and higher bandwidth servers such as Romley, industry analysts predict a 20x increase in 10GBASE-T adoption by 2013, as data centers upgrade to higher densities. Broadcom's new BCM84844 and BCM84846 deliver lower power while offering pin compatibility to previous Broadcom devices (BCM84834 and BCM84836) and integration with Broadcom's broad portfolio of switch, controller, and adapter solutions. This includes PHY drivers within Broadcom's Software Development Kit (SDK) and common implementations of MACsec and 1588v2 PTP.
