BCM5316X
Description
2.5GbE Multiport Switch Series with
High-Speed 10GbE Uplinks
The Broadcom® BCM5316X family of 2.5GbE switches is designed for high-
end and cost-effective multi-Gigabit-Ethernet (multi-GbE) applications
in the SMB, Industrial, and service provider markets. The switch family
supports four 2.5GbE SGMII+ ports, two 2.5GbE/10GbE XFI/SFI ports, and
eight 10/100/1000BASE-T ports with integrated GPHYs.
The BCM5316X switch family is based on the industry-leading 28 nm
RoboSwitch™ architecture, also known as Robo-2. This switch family
integrates the powerful ARM Cortex-M7 CPU that enables customers to
design switching platforms without adding an external processor. These
products are also equipped with the high-end forwarding mechanisms
required in many advanced applications. These mechanisms include an
advanced QoS engine, flexible content filter processor (CFP), sophisticated
VLAN manipulation capability, security features, packet synchronization for
time-sensitive networks, and many more.
The BCM5316X family of switches is supported by multiple software
packages designed for various applications. Basic, unmanaged software
can be used to construct unmanaged switches with basic functionalities
and no VLAN segregation. Web-managed software (such as ROBO-OS™)
can be used to build web-controlled switches while full-featured SDK
software can be used to construct managed devices that are controlled by
an external CPU. For example, home gateways and Ethernet MDU switches
can connect the BCM5316X switches to an external PON or DSL SoC.
The BCM5316X family of switches can be used to construct standalone
platforms with low port-count configuration (up to 15 ports), or a cascaded
design with double port-count switches by connecting two devices back-
to-back.
The BCM5316X switches are offered to customers in commercial-grade
ambient temperature.
Key Features
• Four 1GbE/2.5GbE SGMII+ ports.
• Two 2.5GbE/10GbE XFI/SFI ports.
• Up to eight 10/100/1000BASE-T
ports with integrated GPHYs.
• An integrated ARM Cortex-M7 CPU.
• An RGMII, MII, and RvMII port to
connect to an external CPU (or to
be used as a 1GbE customer port).
• Cascading that enables creation of
unified, single-CPU managed, 15- to
28-port switch.
• Support for advanced QoS, CFP,
VLAN manipulation, up to L4
classification via CFP, and Time
Sensitive Networking (TSN).
• Support for the IEEE 802.1BR port
extender.
• Power-saving green technology
per IEEE 802.3az Energy Efficient
Ethernet.
• Support for both commercial (0°C
to 70°C) and industrial (−40°C to
+85°C) ambient temperature.
Benefits
• Support for cascading mode that enables the creation of a unified,
single-CPU managed, 16- to 26-port switch.
• Support for high-end QoS capabilities with hierarchical scheduling, eight
egress buffer queues per port each with its own shaper, WRED and Tail-
drop congestion avoidance, and dual
leaky bucket
ingress rate limiters
(also known as policers).
• Advanced CFP (such as an access-list engine) that can classify up to L4
headers.
• Support for virtual switching instances (VSI) for explicit segregation of
bridging domains with advanced VLAN translation and encapsulation
(for example, MAC-in-MAC).
Applications
• Industrial Ethernet
• Unmanaged/web-managed/
managed SMB switches
• Home gateway MDU
• Port extender

Product Brief
Benefits (con’t)
• Port-extender support, per IEEE 802.1BR, for designing modular chassis devices or
pizza box
platforms with
remote port extensions.
• Advanced TSN protocol support, such as IEEE 802.1Qav, 802.1Qbv, 802.1ASrev, and 802.1Qci, for scheduling time-
critical traffic streams across an entire network domain.
• Delivered with unmanaged software, web-managed software, or two different managed SDK software
(RoboSwitch SDK and Network Switch SDK).
