Data Sheet BCM53118 Multiport Gigabit Ethernet Switches GENERAL DESCRIPTION FEATURES The Broadcom BCM53118 is a highly integrated, Nine 10/100/1000 media access controllers cost-effective unmanaged-smart gigabit switch. The Eight port 10/100/1000BASE-T/TX transceivers switch design is based on the field-proven, industry- One GMII/RGMII/MII/RvMII/TMII interface for an leading ROBO architecture. This device combines all in-band management port (IMP) for connection the functions of a high-speed switch system including to a CPU/management entity without PHY packet buffers, PHY transceivers, media access IEEE 802.1p, MAC, Port, TOS, and DiffServ QoS controllers (MACs), address management, port- for four queues, plus two time sensitive queues based rate control, and a non-blocking switch fabric Port-based VLAN into a single 65 nm CMOS device. Designed to be fully IEEE 802.1Q-based VLAN with 4K entries compliant with the IEEE 802.3 and IEEE 802.3x specifications, including the MAC-control PAUSE MAC-based trunking with automatic link failover frame, the BCM53118 provides compatibility with all Port-based rate control industry-standard Ethernet, Fast Ethernet, and Port mirroring Gigabit Ethernet (GbE) devices. BroadSync HD The BCM53118 has a rich feature set suitable for not - Timestamp tagging at MAC interface only standard GbE connectivity for desktop and - Time-aware egress scheduler laptop PCs, but also for next-generation gaming DOS attack prevention consoles, set-top boxes, networked DVD players, and - Support IPv6 home theater receivers. It is also specifically IGMP snooping, MLD snooping support designed for next generation SOHO/SMB routers and gateways. Green mode support Spanning tree support (multiple spanning trees The BCM53118 contains eight full-duplex 10/100/ up to eight) 1000BASE-TX Ethernet transceivers. In addition, the Loop detection for unmanaged configurations BCM53118 has one GMII/RGMII/MII/RvMII/TMII with Broadcoms patented LoopDTech interface for the CPU or a router chip, providing technology flexible 10/100/1000-Mbps connectivity. CableChecker with unmanaged mode support The BCM53118 provides 70+ on-chip MIB counters to Double tagging/QinQ collect receive and transmit statistics for each port. IEEE 802.3as support The BCM53118 is available in commercial IEEE 802.3x programmable per-port flow control temperature (C-Temp) rated packages. The and backpressure, with IEEE 802.1x support for commercial-grade BCM53118 is provided in a secure user authentication 256-pin eLQFP (28 mm 28 mm) package.
