BCM5680

8-Port Gigabit Switch-on-a-Chip

The Broadcom BCM5680 represents the highest level of cost-reduction and integration available for the Gigabit Ethernet market. A Broadcombased eight-port gigabit switch reduces today's costs by as much as 50% over competing solutions.

The PCI interface provides a high-speed, flexible mechanism for network system management. Its ability to run either 33 MHz or 66 MHz gives users the flexibility to choose between bandwidth and cost when designing a managed solution. Integrated features such as Scatter/Gather DMA supports advanced management software requirements. Alternatively, an I2C compatible interface is supported.

  • Switch fabric to deliver 12-Mpps switching performance, providing line rate throughput independent of protocol layer processed
  • Layer 2 through 7 filtering and ContentAware™ packet classification, at full line rate on all ports
  • Represents the highest level of silicon integration achieved for a complete eight-port gigabit switch, integrating the switch fabric, MACs, address tables and packet buffering functions.
  • The highly programmable filter engine (FFP) supports wire-speed pack-by-packet filtering and classification, making the BCM5680 the ideal choice for sophisticated switching applications.
