A member of Broadcom's third generation of Gigabit Ethernet PHYs, the BCM5482 consists of two complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip. The BCM5482 is optimized for low power and small footprint size to reduce design complexity for space-constrained IP phone applications. For 10/ 100BASE-TX applications, the single package offers a compelling advantage over two single devices for Gigabit uplinks.
The BCM5482 DSP-based architecture and advanced power management techniques combine to achieve robust and low-power operation over existing Category 5 twisted-pair wiring. The BCM5482 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). With the industry's lowest power at 600 mW per port, the BCM5482 assists in reducing the power distribution requirements of IP phone systems. In addition, the BCM5482 has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications.
