BCM53118

Description

The BCM53118 is a highly integrated, cost-effective, gigabit switch. The switch design is based on the field-proven industry-leading BCM5398. The BCM53118 combines all the functions of a high-speed switch system, including eight full-duplex 10/100/1000BASE-T/TX Ethernet transceivers, packet buffer, Media Access Controllers (MACs), and a non-blocking switch fabric, into a single 65-nm LP CMOS device. In addition, the BCM53118 has one GMII/RGMII/MII/RvMII interface for a CPU or a wireless/DSL/cable router chip. It complies with the IEEE 802.3™ and IEEE 802.3x specifications, including the MAC control PAUSE frame, providing compatibility with all industry-standard Ethernet, Fast Ethernet, and Gigabit Ethernet (GbE) devices.

The BCM53118 is packed with features, including VLAN, VLAN double tagging, per port QoS, jumbo frame support, DOS prevent engine, per port rate control, and MIBs management. BCM53118 also includes two Broadcom patented technologies, LoopDTech and CableChecker, that are designed to lower the human effort for troubleshooting cable problems and loops during installation and for post-installation support.
