BCM5482A2KFBG

Drivers, Receivers, Transceivers Overview

The BCM5482A2KFBG is a dual-port 10/100/1000BASE-T Gigabit Ethernet transceiver manufactured by Broadcom Limited. It integrates two complete Gigabit Ethernet transceivers on a single monolithic CMOS chip using a 0.13-micron process. The device supports data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s with RGMII, SGMII, and SerDes MAC interfaces. Power consumption is rated at 600 mW per port. It operates within standard IEEE 802.3, 802.3u, and 802.3ab specifications.
