BCM5248XA4KFBG Description

Short technical summary and product information.

The Broadcom BCM5248XA4KFBG is a single-chip octal Fast Ethernet transceiver designed for high-density switch applications. It integrates eight independent 10/100 Mbps transceivers compliant with IEEE 802.3 standards, supporting 10BASE-T, 100BASE-TX, and 100BASE-FX. Key features include HP Auto-MDIX for automatic cable pair correction, Advanced CableChecker diagnostics for fault detection, and SMII/SSSMII interfaces for flexible MAC connections. The device operates with a core supply of 1.8V and I/O supply of 2.5V, consuming only 200 mW per port. It is available in QFP or BGA packages with a footprint of 14 mm x 20 mm for eight ports. The transceiver is optimized for use with Broadcom's StrataSwitch family and is suitable for Fast Ethernet switches, enterprise networks, and fiber optic links.
