DataSheet BCM53128 Multiport Gigabit Ethernet Switches GENERAL DESCRIPTION Port-based VLAN The Broadcom BCM53128 is a highly integrated, IEEE 802.1Q-based VLAN with 4K entries cost-effectiveunmanaged-smartgigabitswitch.The switch design is based on the field-proven, industry- MAC-based trunking with automatic link failover leading ROBO architecture. This device combines Port-based rate control all the functions of a high-speed switch system Port mirroring including packet buffers, PHY transceivers, media BroadSync HD for IEEE 802.1AS support access controllers (MACs), address management, Timestamp tagging at MAC interface port-based rate control, and a non-blocking switch Time-aware egress scheduler fabric into a single 65-nm CMOS device. Designed to be fully compliant with the IEEE 802.3 and DOS attack prevention IEEE 802.3x specifications, including the MAC- Support IPv6 control PAUSE frame, the BCM53128 provides IGMP snooping, MLD snooping support compatibility with all industry-standard Ethernet, Green mode support Fast Ethernet, and Gigabit Ethernet (GbE) devices. Spanning tree support (multiple spanning trees The BCM53128 has a rich feature set suitable for up to eight) not only standard GbE connectivity for desktop and Loop detection for unmanaged configurations laptop PCs, but also for next-generation gaming with Broadcoms patented LoopDTech consoles, set-top boxes, networked DVD players, technology and home theater receivers. It is also specifically CableChecker with unmanaged mode support designed for next generation SOHO/SMB routers and gateways. Double tagging/QinQ IEEE 802.az EEE (Energy Efficient Ethernet) The BCM53128 contains eight full-duplex 10/100/ support 1000BASE-TX Ethernet transceivers. IEEE 802.3as support TheBCM53128provides70+on-chipMIBcounters to collect receive and transmit statistics for each IEEE 802.3x programmable per-port flow control port. and backpressure, with IEEE 802.1x support for secure user authentication The BCM53128 is available in commercial EEPROM, MDC/MDIO, and SPI Interfaces temperature(C-Temp)andindustrialtemperature(I- Temp) rated packages. The BCM53128 is provided Serial Flash Interface for accessing embedded in a 256-pin eLQFP (28 mm x 28 mm) package. 8051 processor 4K entry MAC address table with automatic learning and aging FEATURES 192 KB packet buffer Nine 10/100/1000 media access controllers 256 multicast group support Eight port 10/100/1000BASE-T/Tx transceivers Jumbo frame support up to 9720 bytes One GMII/RGMII/MII/RvMII/TMII/RvTMII Serial and parallel LED interface interface for an in-band management port (IMP) 1.2V for core and 3.3V for I/O for connection to a CPU/management entity JTAG support without PHY 256 eLQFP IEEE 802.1p, MAC, Port, TOS, and DiffServ QoS for four queues, plus two time sensitive queues 53128-DS07-R Corporate Headquarters: San Jose, CA April 6, 2016 Broadcom ConfidentialFigure 1: Functional Block Diagram 2016 by Broadcom.
