BCM5482A1KFB Description

Short technical summary and product information.

The BCM5482A1KFB is a dual-port 10/100/1000BASE-T Gigabit Ethernet transceiver from Broadcom. It integrates two independent transceivers supporting 10BASE-T, 100BASE-TX, and 1000BASE-T standards, with half-duplex and full-duplex operation at all speeds. The device offers flexible MAC interface options including RGMII, SGMII, and SerDes, enabling connectivity to a wide range of Ethernet controllers and switches.

Key electrical specifications include typical power consumption of 600 mW per port, jumbo frame support up to 10 kB, and advanced features such as CableChecker diagnostics for cable plant analysis, auto MDI/MDIX crossover, and over 3 kV cable-sourced ESD tolerance. The transceiver is fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards.

The BCM5482A1KFB is housed in a 121-pin BGA package, suitable for surface-mount assembly. Its dual-port integration and low power make it ideal for space-constrained applications such as IP phones, 10/100Base-TX uplinks, and compact networking equipment. The device also supports fiber connectivity in RGMII mode and includes IEEE 1149.1 JTAG boundary scan for manufacturing test.
