BCM5396

BCM5396 ® 16-GE PORT SWITCH WITH INTEGRATED SerDes FEATURES • Eighth-generation switch on a chip • Integrates • One GMII/RGMII/RvMII interface • Seventeen MACs (802.x compliant) with support for 9-KB jumbo frames • Sixteen SGMII/SerDes interfaces and 256-KB packet buffer memory • Non-blocking 17-Gigabit Ethernet fully integrated switch fabric • SPI Interface for easy setup and managed operation • Classifies packets using four 802.1p QoS or DiffServ priority queues • VLAN 4k 802.1Q or port-based support SUMMARY OF BENEFITS • Enables a new generation of lower-cost switches with Gigabit • • • • • • • Ethernet connectivity and much smaller form factors. Uses field-proven industry-standard Gigabit Ethernet SerDes which lowers overall system interoperability and reliability risks. Provides the most cost-effective Gigabit Ethernet connectivity to the desktop and control plane for all remote, branch, and Enterprise needs. 802.1Q tag VLAN, trunking, and 802.1p priority enables the switch to be designed into a wide variety of applications from unmanaged to websmart to managed switch. Jumbo frame support allows the device to be connected to corporate server farms and networks while maintaining maximum TCP/IP performance. CPUs are not required to initialize and run in cost-sensitive unmanaged applications, providing true plug-and-play connectivity. Suitable for fully managed applications due to support for Spanning Tree and 802.1x MAC security SGMII interfaces ensure superior EMI performance and lowest possible number of required board layers while enabling connections to industry-standard physical layer devices (e.g., BCM5464R) Lowest possible system cost through minimized number of external components. Higher system reliability and noise reduction due to elimination of component with lowest MTBF (the fan). • Supports up to 4k unicast MAC addresses • Supports MAC-based port aggregation (trunking) • Flow control • Full-duplex (802.3x) and half-duplex options support • Supports automatic address learning and aging • Support for Spanning Tree and Rapid Spanning Tree • • • • Low power 0.13 µm 1.2 V CMOS core:
