BCM5482A1KFBG Description

Short technical summary and product information.

The BCM5482A1KFBG is a dual-port 10/100/1000BASE-T Gigabit Ethernet transceiver from Broadcom. It integrates two full-featured transceivers supporting 10BASE-T, 100BASE-TX, and 1000BASE-T operation. The device offers flexible MAC interface options including RGMII, SGMII, and SerDes, enabling connection to a wide range of Ethernet controllers and switches.

Electrical characteristics include 600 mW typical power consumption per port, jumbo frame support up to 10 kB, automatic MDI/MDIX crossover at all speeds, and advanced power management. The transceiver is fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards. It also features CableChecker diagnostics for cable plant analysis and IEEE 1149.1 JTAG boundary scan for manufacturing test.

The device is packaged in a 121-pin BGA (121-BGA) and is surface mount compatible. It is designed for space-constrained applications such as IP phones and embedded systems requiring dual-port Ethernet connectivity. The low-power CMOS process (0.13 µm) and compact package help reduce system BOM cost and simplify design.
