Ultra-Low-Power Five-Port GbE Time Sensitive Networking Switch

Currently Viewing:

The Broadcom® BCM53154 is a next-generation ultra-low-power five-port GbE switch. The BCM53154 is based on the new 28-nm RoboSwitch™ 2 architecture and focuses on power-sensitive applications up to five ports—specifically daisy-chain and star topologies in industrial environments as well as low port count unmanaged and web-managed SMB switches.

The BCM53154 supports four 10/100/1000BASE-T ports with integrated GPHYs, a single 1GbE/2.5GbE SGMII port, and a single RGMII 1GbE port.

The BCM53154 is designed for next-generation cost-sensitive applications in the Industrial and SMB markets that require advanced forwarding engines that were not available in prior ICs. Specifically, this new switch supports Time-Sensitive Networking (TSN) and low-latency cut-through forwarding technologies that are essential in many of today’s Industrial market segments. The BCM53154 also supports the new IEEE 802.1BR Port-Extender standard that enables the construction of large, yet extremely cost-effective, distributed SMB switching platforms.

Users of the BCM53154 can take advantage of the IC-integrated ARM CPU to build a complete SMB or Industrial switching solution without adding an external processor. More so, for software needs users can utilize the RoboSwitch 2 ROBO-OS™ operating system and significantly reduce their time-to-market with the new hardware.

The BCM53154 is pin-to-pin compatible to RoboSwitch 2 devices BCM53112 and BCM5316X. This compatibility enables customers to easily build a full portfolio of industrial and SMB switches with almost no changes to their main PCBs. The new portfolio can support any speed from 100 Mb/s to 10GbE and any port count, from as small as 3-port switches up to 24-port switches by cascading two BCM53162 devices.

The BCM53154 supports many high-end features such as Virtual Switching Instances (VSI) for improving VLAN segregation for security-enhanced solutions, advanced QoS mechanism with ingress and egress rate-limiting, and a Content Field Processor (CFP) that enable users to classify traffic according to OSI model L1 to L4 fields.

The BCM53154 is supported by all software suites designed for the RoboSwitch 2 architecture. Basic, unmanaged software can be used to construct unmanaged switches with basic functionalities and no VLAN segregation. Web-managed software (such as the ROBO-OS operating system) 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.
