BCM5676中文资料BCM5676 4-PORT, 96-GBPS SWITCH FABRIC数据手册Broadcom规格书

描述 Description

General Description
The Broadcom BCM5676 switch fabric is the central component of the modular and highly scalable StrataXGS™ Gigabit Ethernet switch architecture. StrataXGS components can be applied in a wide variety of configurations, enabling system designers to strategically balance cost, port density, and performance in the products they build.FEATURES
• Four 10-Gbps and 12-Gbps (HiGig+™) configurable switch fabric ports
• Nonblocking, 96-Gbps wirespeed, backplane/switch fabric performance
• Forwarding rate of 72 million packets/second
• Multistage switch fabric scalable up to 750 Gbits
• Eight integrated high-speed XAUI interfaces
• Eight programmable priority queues per port
• Port trunking (up to 4 ports) and mirroring across multiple devices
• Hot-swap capable with AC coupling
• Supports redundancy on linecards for chassis-based applications
• Advanced diagnostic features including IEEE 1149.1 boundary scan, JTAG, and extensive BIST functionality
• Resilient link configuration through active multi-path forwarding
• PCI and I2C interface
• Broadcom switch API compatibility
• Advanced 0.13-µm CMOS technology
• Small 600-pin EBGA package; pin-compatible with BCM5671
• Low power consumptionSUMMARY OF BENEFITS
• System vendors can build high-performance, high-density Gigabit Ethernet LAN switches in several form factors
• Very low latency and advanced QoS enable seamless integration of voice, video, and data traffic
• Built-in high-speed XAUI interfaces with Broadcom-unique SerDes technology eases and accelerates system design, while reducing cost and conserving board space
• Large internal data buffer memory eliminates the need for expensive external memory
• Drives up to 10m of low-cost copper cables backplane and stacking support
• Broadcom switch API compatibility enables reuse of resources and fast time-to-marketTARGET APPLICATIONS
• Switch fabric in modular Gigabit Ethernet chassis
• Switch fabric in high-port-count stand-alone or stackable Gigabit Ethernet switches
• Switch fabric for in-server switch blade applications
• Packet-based switch fabric in telecom applications
