PHY 1-CH 1000Mbps 121-Pin BGA

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.The BCM5482 supports the RGMII, SGMII, and SerDes MAC interfaces. The RGMII, SGMII, and serial SerDes inteerfaces are reduced-pin-count (12, 6, and 4, respectively, versus 25) versions of the GMII. The RGMII clock timing can be adjusted to eliminate the board trace delays required by the RGMII specification. These reduced-pincount interfaces simplify design and lower system cost by reducing the number of layers required for signal routing. In addition, these interfaces allow fewer pins at the MAC/switch, which reduces the MAC/switch cost by enabling smaller die sizes than would be possible with full GMII. This device is another member of Broadcom’s 0.13-µm Gigabit Ethernet copper PHY family, joining more than 25 other quad and single products. The 0.13-µm process is the optimal process that offers the best performance, lowest cost, and lowest power for Gigabit Ethernet copper solutions.
