The BCM5464 consists of four complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip. The BCM5464 is optimized for low power and small footprint size to enable high port density applications. By lowering system cost and reducing power dissipation by nearly 30%, the BCM5464 enables a new class of cost-effective Gigabit Ethernet equipment, driving the delivery of Gigabit bandwidth to the desktop.
The BCM5464'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 BCM5464 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 key to implementing high-density Gigabit switches, and at less than 700mW per port, the BCM5464 has the industry's lowest power. In addition, the BCM5464 has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications.
