BCM5464SR

Description

The BCM5464SR consists of four complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip, and is a member of Broadcom's QuadSquad™ family of quad Gigabit Ethernet PHYs. The BCM5464SR is optimized for low-power and small footprint size to enable high port density applications. The BCM5464SR enables a new class of cost effective Gigabit Ethernet equipment by lowering system cost and reducing power dissipation by nearly 25%, driving the delivery of Gigabit bandwidth to the desktop.

The BCM5464SR digital signal processor based architecture and advanced power management techniques combine to achieve robust and low-power operation over the existing Category 5 twisted-pair wiring. The BCM5464SR architecture not only meets the requirements of IEEE's 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 the BCM5464SR has the lowest power in the industry at less than 750 mW per port. In addition, the BCM5464SR has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications.
