BCM5482A2KFBG

BCM5482A2KFBG Description

The BCM5482A2KFBG from Broadcom Limited is a high-performance Ethernet transceiver designed for robust networking applications. This surface-mount IC integrates 2 drivers and 2 receivers, supporting both full-duplex and half-duplex communication modes. Packaged in a 121-ball BGA (Ball Grid Array), it complies with ROHS3 and REACH environmental standards, ensuring suitability for modern electronics. Although marked as obsolete, its reliability and compliance with ECCN 5A991B1 and HTSUS 8542.39.0001 make it a viable choice for legacy systems. With a Moisture Sensitivity Level (MSL) of 3 (168 hours), it requires careful handling during assembly.

BCM5482A2KFBG Features

• Dual-Channel Operation: Integrates 2/2 drivers/receivers for bidirectional data transmission.
• Flexible Duplex Modes: Supports full-duplex (high-speed) and half-duplex (legacy) Ethernet protocols.
• Robust Compliance: Meets ROHS3, REACH, and ECCN 5A991B1 standards for global deployment.
• High-Density Packaging: 121-BGA package optimizes board space in compact designs.
• Industrial Reliability: MSL 3 rated for controlled environmental handling.
• Broadcom Legacy Support: Ideal for maintaining or upgrading older systems requiring proven transceiver performance.

BCM5482A2KFBG Applications

• Enterprise Networking: Used in switches, routers, and hubs requiring stable Ethernet connectivity.
• Industrial Automation: Deployed in PLC (Programmable Logic Controller) systems for robust data transmission.
• Telecommunications: Supports legacy telecom infrastructure due to its half-duplex compatibility.
• Embedded Systems: Suitable for FPGA/ASIC-based designs needing reliable PHY-layer interfaces.
• Retrofit Projects: Cost-effective solution for upgrading older hardware without redesigning entire PCBs.

Conclusion of BCM5482A2KFBG

The BCM5482A2KFBG remains a technically sound choice for applications demanding dual-channel Ethernet transceivers with flexible duplex modes. While obsolete, its compliance, compact BGA package, and Broadcom’s legacy support make it valuable for industrial, telecom, and embedded systems. Engineers seeking a balance between performance and backward compatibility will find this IC particularly useful in maintenance or upgrade scenarios.
