Seven-Port Managed 10/100 RoboSwitch™

Currently Viewing:

Feature-enhanced seven-port switch to the industry-leading BCM5325E RoboSwitch™.
This device combines all the functions of a high-speed switch system, including packet buffers, PHY transceivers, Media Access Controllers (MACs), address management and a non-blocking switch fabric, into a 65 nm LP process. The BCM53101 contains five full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers connected to the five on-chip 10/100 MACs. In addition, a sixth 10/100 MAC is available through the MII/RvMII interface. The BCM53101 also features a 10/100/1000 MAC, which can be used to connect to an external CPU via the RGMII/MII/RvMII interface.


  • Highly integrated 65 nm process, seven-port 10/100 switch integrates:
    -Five 10/100 MACs with five integrated 10/100 PHYs
    -One 10/100 MAC with MII/RvMII/RMII interface
    -One 10/100/1000 MAC with RGMII/MII/RvMII/RMII interface
  • 2 KB max frame size and 2K MAC performance
  • Enables next-generation six Fast Ethernet + one Gigabit Ethernet switches with enhanced L2+ features
  • High level of integration provides for cost-effective designs


  • Home and Small Business Servers (switching)
