Each port has the flexibility to support either 10Gbps serial, XAUI or CX4. In addition, the adaptive equalization capability on each port can increase reach for XAUI, CX4 and 10Gbps serial applications, as well as eliminate the need for external re-timer circuits, reducing board space, power consumption and cost. With 10Gbps serial capabilities on each port, the MB8AA3020 allows direct connection to optical XFP modules on any port, eliminating the use of third party SerDes chips. This reduces board complexity, improves cost, and reduces time to market. MB8AA3020 offers a total of 400Gbps of non-blocking aggregate switching capacity in both cut-through and store-and-forward mode of operation. A switching latency of 300ns, including 10GbE SerDes in cut-through mode, makes the switch ideally suited for high-density, latency-sensitive applications. AMC Security Chip AMC Traffic Manager As a result of being fabricated with 90nm technology, the MB8AA3020 provides the lowest-power-consumption highest-density 10GbE switch chip in the industry, making the MB8AA3020 well suited for high density, low-power applications. The Fujitsu MB8AA3020 20-port 10GbE switch chip provides eight priority classifications per port, which allows priority switching based on DiffServ, MAC address, VLANs, extended VLANs and ports. The MB8AA3020 also provides several carrier-grade Ethernet features including priority PAUSE, backward congestion notification, and early-class watermark capabilities for congestion notification. These features in combination with its large buffer memory, allow the MB8AA3020 to handle both best-effort and guaranteedhigh-availability customer traffic in a single chip. In addition to its standard 4K VLAN and Q-in-Q capabilities, the chip provides 64 additional user VLAN addresses, which can be used to logically partition a network without the use of Q-in-Q. 10GBE 1 x 10GBE XAUI or 1 x 10GBE Serial + 10/100/GBE 16 x 10GBE XAUI or 16 x 10GBE Serial AMC 10GBE Network Processor Processor Carrier Card MB8AA3020 The MB8AA3020 possesses two 10/100/1000 Ethernet management interfaces, which provide an agnostic interface to the chip, allowing it to communicate with any third-party processor chip. The MB8AA3020 also supports I2C interfaces, MDIO interfaces and EEPROM interfaces for low-speed communication with third-party external devices. The Fujitsu MB8AA3020 module is the industry’s most advanced, high-density switching architecture, providing a low-latency, low-power, feature-rich switch in a small form-factor footprint. The MB8AA3020 is well-suited for next-generation backplane fabric applications seen in AdvancedTCA, µTCA and blade server platforms. The Fujitsu MB8AA3020 10Gbps 20-port Ethernet switch provides an integrated on-chip micro-engine which executes commands sent by the Ethernet management interface. This simplifies software development, increases flexibility and reduces time to market. FUJITSU MICROELECTRONICS AMERICA, INC. Corporate Headquarters 1250 E.
