10/100/1000BASE-T Gigabit Copper Transceiver
The BCM5421 is a fully integrated 10/100/1000BASE-T Gigabit Ethernet transceiver. The BCM5421 is optimized for low power and small footprint size to enable Network Interface Card (NIC) and uplink applications. By lowering system cost and reducing power dissipation by nearly 50%, the BCM5421 enables a new class of cost-effective Gigabit Ethernet equipment, driving the delivery of Gigabit bandwidth to the desktop.
The BCM5421's Digital Signal Processor based architecture and advanced power management techniques combine to achieve robust and low power operation over the existing CAT 5 twisted pair wiring. The BCM5421 architecture not only meets the requirements of 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 a key factor in implementing Gigabit small form factor NICs and uplinks and, at 1W per port, the BCM5421 dissipates nearly half the power of previous Gigabit PHY transceivers. For NIC applications, support for Wake on LAN enables compliance with PCI 2.2 and PC99/PC2000. In addition, the BCM5421 has extremely low EMI emissions, which reduces the design constraints required to meet EMI emissions specifications.
