High speed switch system offers high level of integration for cost-effective designs

Available from Digi-Key, the feature-enhanced seven-port BCM53101 RoboSwitch from Broadcom 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 65nm LP process. It 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 device also features a 10/100/1000 MAC, which can be used to connect to an external CPU via the RGMII/MII/RvMII interface.
