Single-Chip L2+ Managed Switch with 48 10/100 Ports + Four GbE Ports

The BCM5348 is designed based on the field-proven industry leader ROBOswitch®. This device combines all the functions of a high-speed switch system including packet buffers, PHY transceivers, media access controllers, address management, and a nonblocking switch fabric into a single 0.13 μm CMOS device. It complies with IEEE 802.3 specifications, including the MAC control PAUSE frame and auto-negotiation subsections, providing interoperability with all industry-standard Ethernet, Fast Ethernet, and Gigabit Ethernet devices.

The BCM5348 is the industry's first Ethernet to integrate forty-eight FE MACs and five GbE MACs and twenty-four full-duplex 10BASE-T/100BASE-TX/FX Fast Ethernet transceivers in a single chip. The BCM5348 also supports four SGMII interfaces, providing flexible 10/100/1000BASE-TX and fiber connectivity.
