BCM5461SA3KFBG

BCM5461SA3KFBG is a 10/100/1000base-t gigabit copper transceiver. It is optimized for low power and small footprint size to enable backplane and uplink applications. By lowering system cost and reducing power dissipation by nearly 30%, the BCM5461 enables a new class of cost-effective gigabit ethernet equipment, driving the delivery of gigabit bandwidth to the desktop. The BCM5461’s digital signal processor-based architecture and advanced power management techniques combine to achieve robust and low power operation over the existing CAT 5 twisted-pair wiring. The BCM5461 architecture not only meets the requirements of 802.3, 802.3u, and 802.3ab, but maintains the industry’s highest level of margin over IEEE requirements for Echo, NEXT, and FEXT. Low power is a key factor in implementing Gigabit small form factor NICs and uplinks and, at less than 700 mW per port, the BCM5461 has the industry's lowest power.
