BCM54684 General Description
The BCM54684 is second-generation state-of-the-art 65-nm octal Gigabit Ethernet transceiver. It is the world's first device with eight complete 10/100/1000BASE-T GbE transceivers and two QSGMII MAC interface integrated on a single monolithic CMOS chip. The BCM54684 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 15 percent compared to previous generation PHY products, the BCM54684 enables a new class of cost-effective GbE equipment, driving the delivery of GbE bandwidth to the desktop.
The BCM54684 DSP-based architecture and advanced power management techniques combine with enhanced analog front-end design to achieve robust and low-power operation over existing Category 5 twisted-pair wiring. The BCM54684 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 GbE switches, and the BCM54684 has the smallest footprint and lowest power in the industry at less than 420 mW per port.
