BCM5481

Description

The BCM5481 is optimized for low power and small footprint size to enable uplink and general Gigabit Ethernet connectivity applications. By lowering system cost and reducing power dissipation, the BCM5481 enables a new class of cost-effective Gigabit Ethernet equipment, driving the delivery of Gigabit bandwidth to the desktop.

The BCM5481 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 BCM5481 architecture also meets the requirements of 802.3, 802.3u, and 802.3ab, but maintains some of the industry's highest margins 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 BCM5481 is one of Broadcom's lowest power GbE solutions. Also, the BCM5481 has extremely low EMI emissions, which reduces the design constraints required to meet EMI emissions specifications.
