BCM5488R

Description

The BCM5488R consists of eight complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip. The BCM5488R 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 percent, the BCM5488R enables a new class of cost-effective Gigabit Ethernet equipment, driving the delivery of Gigabit Ethernet bandwidth to the desktop.

The BCM5488R DSP-based architecture and advanced power management techniques combine to achieve robust and low-power operation over existing Category 5 twisted-pair wiring. The BCM5488R 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 (FEXT). Low power is the key to implementing high-density Gigabit Ethernet switches, and the BCM5488R has the lowest power in the industry at less than 600 mW per port. In addition, the BCM5488R has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications.
