BCM5466R

Description

A member of Broadcom's QuadSquad™ family of quad Gigabit Ethernet PHYs, the BCM5466R consists of four complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip. The BCM5466R is optimized for low power and small footprint size to enable high-port-density applications. The BCM5466R enables a new class of cost-effective Gigabit Ethernet equipment by lowering system cost and reducing power dissipation by nearly 25 percent, driving the delivery of Gigabit Ethernet bandwidth to the desktop.

The BCM5466R DSP-based architecture and advanced power management techniques combine to achieve robust and low-power operation over existing Category 5 twisted-pair wiring. The BCM5466R architecture not only meets the requirements of IEEE 802.3, IEEE 802.3u, and IEEE 802.3ab, but also maintains the industry's highest level of margin over IEEE requirements for echo, near-end crosstalk (NEXT), and far-end crosstalk (FEX)T. Low power is key to implementing high-density Gigabit Ethernet switches, and the BCM5466R has the lowest power in the industry at 750 mW per port. In addition, the BCM5466R has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications.
