DUAL-PORT 10/100/1000BASE-T GIGABIT ETHERNET TRANSCEIVER

A member of Broadcom’s third generation of Gigabit Ethernet PHYs, the BCM5482S consists of two complete 10/100/1000BASE-T Gigabit Ethernet transceivers integrated on a single monolithic CMOS chip. The BCM5482S is optimized for low power and small footprint size to reduce design complexity for high-density uplink applications. For high-density uplink applications, the single package offers a compelling advantage over two single devices for Gigabit uplinks.
