Data Sheet BCM53134M Multiport Ultra Low-Power Gigabit Ethernet Switch General Description Features Six 10/100/1000 media access controllers The Broadcom BCM53134M is an ultra low-power, highly Four-port 10/100/1000 transceivers for TX integrated, cost-effective smart-managed Gigabit switch. One RGMII interface for an IMP for connection to a The switch design is based on the field-proven, industry- CPU/management entity without PHY leading ROBO architecture. This device combines all the One RGMII interface for a connection to another PHY, functions of a high-speed switch system including packet CPU, or modem buffers, PHY transceivers, media access controllers IEEE 802.1p, MAC Port, TOS, and DiffServ QoS for six (MACs), address management, port-based rate control, and queues, plus two time-sensitive queues a nonblocking switch fabric into a single 28 nm CMOS Port-based VLAN device. Designed to be fully compliant with the IEEE 802.3 IEEE 802.1Q-based VLAN with 4K entries and IEEE 802.3x specifications, including the MAC-control MAC-based trunking with automatic link failover PAUSE frame, the BCM53134M provides compatibility with Port-based rate control all industry-standard Ethernet, Fast Ethernet, and Gigabit Port mirroring (Ingress/Egress) Ethernet (GbE) devices. Supports IPv4 and IPv6 The BCM53134M has a rich feature set suitable for not only Priority modification on egress standard GbE connectivity for broadband home gateways, BroadSync HD for IEEE 802.1AS support desktop, and laptop PCs, but also for next-generation Timestamp tagging at MAC interface gaming consoles, set-top boxes, networked DVD players, Time-aware egress scheduler and home theater receivers. It is also specifically designed DOS attack prevention for next generation SOHO/SMB routers and gateways. IGMP Snooping, MLD snooping support The BCM53134M contains four full-duplex 10/100/ Spanning tree support (multiple spanning treesup to 1000BASE-T Ethernet transceivers. In addition, the eight) BCM53134M has two PHY-less interfaces for the CPU or a Embedded CPU (8051) processor for cable diagnostics router chip, providing flexible 10/100/1000 Mb/s CableChecker with unmanaged mode support connectivity. One RGMII interface can be connected to a Double tagging/QinQ CPU entity and configured as an IMP (In-Band IEEE 802.az Energy Efficient Ethernet (EEE) support Management port). IEEE 802.3x programmable per-port flow control and backpressure, with IEEE 802.1X support for secure The second RGMII interface is available for another PHY, user authentication modem, or CPU connection. EEPROM, MDC/MDIO, and SPI Interface. The BCM53134M provides 70+ on-chip MIB counters to Serial Flash Interface for accessing embedded CPU collect receive and transmit statistics for each port.
