Data Sheet BCM53115S Multiport Gigabit Ethernet Switches GENERAL DESCRIPTION FEATURES The Broadcom BCM53115S is a highly integrated, Seven 10/100/1000 media access controllers cost-effective smart-managed Gigabit switch. The Five-port 10/100/1000 transceivers for TX switch design is based on the field-proven, industry- One GMII/RGMII/MII/RvMII/TMII interface for leading ROBO architecture. This device combines all an inband management port (IMP) for the functions of a high-speed switch system including connection to a CPU/management entity without PHY packet buffers, PHY transceivers, media access controllers (MACs), address management, port- One GMII/RGMII/MII/RvMII/TMII interface for WAN port based rate control, and a non-blocking switch fabric into a single 65 nm CMOS device. Designed to be fully Dual IMP ports support, WAN interface (Port 5) to be IMP port-capable compliant with the IEEE 802.3 and IEEE 802.3x specifications, including the MAC-control PAUSE IEEE 802.1p, MAC Port, TOS, and DiffServ QoS for four queues frame, the BCM53115S provides compatibility with all industry-standard Ethernet, Fast Ethernet, and Port-based VLAN Gigabit Ethernet (GbE) devices. IEEE 802.1Q-based VLAN with 4K entries MAC-based trunking with automatic link failover The BCM53115S has a rich feature set suitable for not Port-based rate control only standard GbE connectivity for desktop and Port mirroring 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 Ingress mirroring designed for next generation SOHO/SMB routers and IGMP Snooping, MLD snooping support gateways. Spanning tree support (multiple spanning trees The BCM53115S contains five full-duplex 10/100/ up to eight) 1000 BASE-TX Ethernet transceivers. In addition, the Loop detection for unmanaged configurations BCM53115S 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. A GMII/ CableChecker with unmanaged mode support RGMII/SGMII/MII/RvMII/TMII interface for the WAN Double-tagging/QinQ port can be configured as an IMP port. IEEE 802.3 as support IEEE 802.3x programmable per-port flow control The BCM53115S provides 70+ on-chip MIB counters and backpressure, with IEEE 802.1x support for to collect receive and transmit statistics for each secure user authentication port. EEPROM, MDC/MDIO, and SPI Interface The BCM53115S is available in industrial 4K entry MAC address table with automatic temperature (I-Temp) and commercial temperature learning and aging (C-Temp) rated packages. The industrial-grade 128 KB packet buffer BCM53115S is provided in a 484-pin PBGA (23 mm x 128 multicast group support 23 mm) package. The commercial-grade BCM53115S Jumbo frame support up to 9720 byte is provided in a 400-pin FBGA (17 mm x 17 mm) 1.2V for core and 3.3V for I/O package.
