BCM5482SHA1KFB

Drivers, Receivers, Transceivers Overview

The BCM5482SHA1KFB is a dual-port Gigabit Ethernet transceiver manufactured by Broadcom Limited. It integrates two complete 10BASE-T, 100BASE-TX, and 1000BASE-T transceivers on a single monolithic CMOS chip. The device supports RGMII, SGMII, and SerDes MAC interfaces, enabling flexible connectivity for copper and fiber uplinks via SFP modules. Operating at data rates of 10 Mbps, 100 Mbps, and 1 Gbps, it consumes 725 mW per port. The component utilizes a 121-pin BGA package and complies with IEEE 802.3, 802.3u, and 802.3ab standards.
