BCM5482A2IFB Description

Short technical summary and product information.

The BCM5482A2IFB is a dual-port integrated 10BASE-T/100BASE-TX/1000BASE-T Gigabit Ethernet transceiver from Broadcom, built on 0.13 µm CMOS technology. Each port consumes 600 mW, enabling low total power dissipation of 1.2 W. The device supports RGMII, SGMII, and SerDes MAC interface options, with line-side SerDes available in RGMII mode. It is fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards.

Key electrical features include automatic MDI/MDIX crossover at all speeds, jumbo frame support up to 10 kB, robust cable-sourced ESD tolerance exceeding 3 kV, and CableChecker diagnostics for detecting cable impairments. The transceiver offers line-side and MAC-side loopback modes and IEEE 1149.1 JTAG boundary scan for testing.

The device is designed for space-constrained applications such as IP phones and Gigabit Ethernet uplinks. It requires dual power rails of 2.5V and 3.3V. The package is a 121-pin BGA measuring 12x12 mm, surface mount with solder ball termination. Operating temperature is industrial grade (I temp).
