BCM54980C1KFBG BCM54980 Gigabit Copper Transceiver

BROADCOM BCM54980C1KFBG BCM54980 Gigabit Copper Transceiver

The BCM54980 consists of eight complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip. The BCM54980 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 compare to previous generation PHY products, the BCM54980 enables a new class of cost-effective Gigabit Ethernet equipment, driving the delivery of Gigabit Ethernet bandwidth to the desktop. 

The BCM54980 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 BCM54980 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, nearend crosstalk (NEXT), and far-end crosstalk (FEXT). Low power is the key to implementing high-density Gigabit Ethernet switches, and the BCM54980 has the smallest footprint and lowest power in the industry at less than 500 mW per port. In addition, the BCM54980 has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications. The BCM54980 provides the highest level of external component integration in the smallest possible package which results in PBC space saving of 40 percent for high density switch applications.

Features

Eight 90-nm CMOS fully-integrated 10BASE-T/100BASE-TX/1000BASE-T Gigabit Ethernet transceivers

Low power: <500 mW per port

Low-power, octal-port integration enables single-row, high-port density switches that lowers system costs by eliminating PCB layers required for routing high-density solutions

Ability to fully swap the order of the twisted-pair input-receive channel and output-transmit channel independent of each other which results in ease of board design and simplifies the lay out in high port density switch designs
