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

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.
