5-GbE PORT SWITCH WITH INTEGRATED SerDes
FEATURES
SUMMARY OF BENEFITS
• Eighth-generation switch on a chip
• Integrates
• One GMII/RGMII/RvMII interface
• Five MACs (802.x compliant) with support for 9-KB jumbo
frames
• Five SGMII/SerDes interfaces and 128-KB packet buffer
memory
• Non-blocking 6-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
• 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: <1.5W Pd.
• Fanless operation support
• Port-based rate control feature with 64 kbps granularity
• 256-pin FBGA package (small form factor 17 mm x 17 mm)
• 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 integration of full MIB counters
• 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).
