Data Sheet BCM53134O Multiport Ultra Low-Power Gigabit Ethernet Switch General Description Features Six 10/100/1000 media access controllers The Broadcom BCM53134O is an ultra low-power, highly Four-port 10/100/1000 transceivers for TX integrated, cost-effective smart Gigabit switch. The switch One RGMII interface for an IMP for connection to a design is based on the field-proven, industry-leading ROBO CPU/management entity without PHY architecture. This device combines all the functions of a One SGMII interface supports 1G/2.5 Gb/s (2.5 Gb/s is high-speed switch system including packet buffers, PHY for 2500BASE-X only) transceivers, media access controllers (MACs), address Supports 2500BASE-X,1000BASE-X, and 100BASE- management, port-based rate control, and a nonblocking FX switch fabric into a single 28 nm CMOS device. Designed to IEEE 802.1p, MAC Port, TOS, and DiffServ QoS for six be fully compliant with the IEEE 802.3 and IEEE 802.3x queues, plus two time-sensitive queues specifications, including the MAC-control PAUSE frame, the Port-based VLAN BCM53134O provides compatibility with all industry- IEEE 802.1Q-based VLAN with 4K entries standard Ethernet, Fast Ethernet, and Gigabit Ethernet MAC-based trunking with automatic link failover (GbE) devices. Port-based rate control The BCM53134O has a rich feature set suitable for not only Port mirroring (Ingress/Egress) standard GbE connectivity for broadband home gateways, Supports IPv4 and IPv6 desktop, and laptop PCs, but also for next-generation Priority modification on egress gaming consoles, set-top boxes, networked DVD players, BroadSync HD for IEEE 802.1AS support and home theater receivers. It is also specifically designed Timestamp tagging at MAC interface for next generation SOHO/SMB routers and gateways. Time-aware egress scheduler The BCM53134O contains four full-duplex 10/100/ DOS attack prevention 1000BASE-T Ethernet transceivers. In addition, the IGMP Snooping, MLD snooping support BCM53134O has two PHY-less interfaces for the CPU or a Spanning tree support (multiple spanning treesup to router chip, providing flexible 10/100/1000 Mb/s eight) connectivity. One RGMII interface can be connected to a Embedded CPU (8051) processor for cable diagnostics CPU entity and configured as an IMP (In-Band CableChecker with unmanaged mode support Management port). Double tagging/QinQ IEEE 802.az Energy Efficient Ethernet (EEE) support The second interface port is available in an SGMII interface IEEE 802.3x programmable per-port flow control and supporting rates of up to 2.5 Gb/s (2.5 Gb/s is for backpressure, with IEEE 802.1X support for secure 2500BASE-X only) that can be connected to optical user authentication modules or any other device with an SGMII interface.The EEPROM, MDC/MDIO, and SPI Interface. BCM53134O provides 70+ on-chip MIB counters to collect Serial Flash Interface for accessing embedded CPU receive and transmit statistics for each port.
