Broadcom BCM53161 A 2.5GE multi-port switch series

The BCM53161/BCM53162 switches support four 2.5GE SGMII+ ports and two 2.5GE/5GE/10GE XFI/SFI ports.

Broadcom’s BCM53161/BCM53162 is a family of 2.5GE switches designed for high-end and cost - effective multi-GE applications in the SMB, Industrial, and service provider markets. The BCM53161/BCM53162 switches support four 2.5GE SGMII+ ports and two 2.5GE/5GE/10GE XFI/SFI ports. BCM53162 also supports eight 10/ 100/1000Base-T ports with integrated GPHYs. This switch family is based on the industry-leading 28 nm RoboSwitch™ architecture, also known as Robo II.

Key features

Two 2.5GE/5GE/10GE XFI/SFI ports.
Up to Eight 10/100/1000Base-T ports with Integrated GPHYs
RGMII, MII, and RvMII interface to an external

Additional features

Four 1GE/2.5GE SGMII+ ports.
Two 2.5GE/5GE/10GE XFI/SFI ports.
Up to Eight 10/100/1000Base-T ports with Integrated GPHYs
RGMII, MII, and RvMII interface to an external
CPU (can also be used as a 1GE customer facing port).
Integrated Arm-Cortex M7 CPU for cost-effective applications.
Support for cascading mode that enables thecreation of a unified, single CPU, managed 16-26 port switch.
Support high-end QoS capabilities with hierarchicalscheduling, eight egress buffer queues per port each with its own shaper, WRED and
Tail-drop congestion avoidance, and dual-leakybucket ingress rate-limiters (also known as policers).
Advanced Compact Filter Processor (CFP), also known as the Access-List engine that can classify L1-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).
Port-Extender support per 802.1BR for design of modular chassis devices or pizza box platforms with remote port extensions.
Advanced Time Sensitive Networking (TSN) protocol support such as 802.1AS to synchronize traffic transmission across entire network domain.
Power-saving green technology per IEEE 802.3az Energy Efficient Ethernet.
Can be delivered with unmanaged software,
Web-Managed software or two different Managed
SDK software (RoboSwitch SDK and Network Switch SDK).
Supports both commercial and industrial temperature grades.

Applications

Unmanaged/Web-Managed/Managed SMB Switch
Home Gateway MDU
Port Extender
Industrial Ethernet

Two types:

BCM53161: 2.5 Gig-Ethernet Robo II switch with 4 x 1000FX/2500FX SGMII+ ports + 2 x 10000FX XFI/SFI ports

BCM53162: 2.5 Gig-Ethernet Robo II switch with 8 x 10/100/1000Base-T ports with Integrated GPHYs

The BCM53161/BCM53162 family of switches is supported by multiple software packages designed for different applications. Basic unmanaged software can be used to construct unmanaged switches with basic functionalities and no VLAN segregation. Web-managed software, also known as Robo-OS™, can be used to build webcontrolled switches, and fully-featured SDK software can be used to construct managed devices that are controlled by an external CPU, for example, home-gateways and MDUs where BCM53161/BCM53162 chips are connected to an external PON or DSL SoC. Broadcom's BCM53161/BCM53162 chips can be used to construct standalone platforms with low port-count configuration (up to 15 ports), or to construct, using a cascaded design, a double port-count switch by connecting two chips backtoback. BCM53161/BCM53162 switches are offered to customers in commercial-grade as well as Industrial- grade temperature ambient.
