Low-power Fast-Ethernet RoboSwitch™-2 with High-Speed 1GbE/2.5GbE Uplink Interfaces;

Currently Viewing:

Broadcom's BCM53112 is a highly integrated Fast-Ethernet switch designed for high-end FE applications. It has eight 10/100BASE-T ports (with integrated EPHYs), four 100FX/1000FX SGMII ports and additional two 1GbE/2.5GbE SGMII+ ports. The switch is optimally designed for Industrial applications that demand advanced Time Sensitive Networking (TSN) and Audio-Video-Bridging (AVB)  support. The device can also be used for next-generation 100Mbps hybrid-speed SMB solutions that require combinations of 100M/1GE/2.5GE ports and are either unmanaged or lightly managed from GUI or from the cloud. 

The BCM53112 is based on the industry-leading 28 nm RoboSwitch™ architecture, also known as Robo-2. The switch integrates a powerful ARM Cortex-M7 CPU that enables customers to design complete SMB and Industrial switches without relying on external processors. The switch is also equipped with high-end forwarding engines that are required in advanced applications. It includes an intelligent QoS mechanism, a flexible compact filter processor (CFP), sophisticated VLAN manipulation capability, security features, packet synchronization for time sensitive networks and more.

The BCM53112 can be purchased with different software packages designed for a multitude of applications. It can be used with basic unmanaged software to design unmanaged switches that require no advanced functionality or VLAN segregation. It can be used with web-managed software to construct a high-end, web-controlled switch, and can also be used with a fully featured SDK software suite to design managed devices that are controlled by an external CPU.
