| BCM5691 (R) SCALABLE 12-PORT GIGABIT ETHERNET MULTILAYER SWITCH FEATURES * 12 10/100/1000 Mbps Ethernet ports supporting both copper and fiber connections * Integrated high-performance SerDes * Gigabit Ethernet SerDes per port * 4-pins per port SGMII interface to Gigabit Ethernet PHYs * 32 million packets/second (line rate) aggregate switching capacity * Supports 8 classes of service (CoS) per port SUMMARY OF BENEFITS * System vendors can build scalable high-performance, high * * * * port density Gigabit Ethernet LAN switches in several form factors. Multiple classes of service (CoS) and very low latency enable the support of VoIP and other voice, video, and data applications. Built-in high-speed serial interfaces with Broadcom-unique SerDes technology eases and accelerates system design, while reducing cost and conserving board space. Broadcom switch API compatability enables software reuse and faster time-to-market Small package and low power enables cost-effective and highperformance system design * Port trunking and mirroring supported across stacked switches * Fully integrated data and address memory on-chip * Advanced packet flow control: * Head of line blocking prevention * Full-duplex flow control (802.3x compatible) * ContentAwareTM network processing per port * Line rate multifield packet classification * Supports IEEE802.1p, TOS/DiffServ, rate limiting, policing, priority tagging, and remapping * Support for jumbo Frames of up to 9 KB TARGET APPLICATIONS * Multilayer switch in modular Gigabit Ethernet switches * High port count stand-alone or stackable Gigabit Ethernet switches * Chassis and in-server switch blade applications * Advanced diagnostic features including IEEE1149.1 JTAG boundary scan and BIST functionality * Low power, enhanced thermal 480-pin EBGA package SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII PCI I2C GPIC FFP GPIC FFP GPIC FFP GPIC FFP GPIC FFP GPIC FFP CMIC L2 Table L3 Table MMU VLAN Table GPIC FFP GPIC FFP GPIC FFP GPIC FFP GPIC FFP GPIC FFP IPMC Table CBP SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII 12-Port Gigabit Ethernet Multilayer Switch OVERVIEW Layer 27 Traffic Classification PCI 32/66 MHz CPU Interface CPU/IO FFP ARL SRAM High speed on-chip memory Packet Buffer MAC(s) Built-in SerDes with SGMII support The BCM5691 network switch is a scalable, modular chip solution with 12 ports. Each of these flexible ports supports Gigabit Ethernet or 10/100 Mbps Ethernet. Additionally, the BCM5691 supports both copper and fiber physical interfaces. The BCM5691 has a fully integrated SerDes functionality consisting of a Gigabit Ethernet or a SGMII PHY interface. The advanced fast filter processor (FFP) provides ContentAwareTM network processing per port. The FFP supports ToS/DiffServ, rate limiting, policing, priority tagging and remapping. The advanced packet filtering and classification functions of the BCM5691 make it ideal for cutting-edge VoIP and firewall applications. The BCM5691 supports advanced packet flow control such as head-ofline blocking prevention and IEEE 802.3x compatible full-duplex control. Moreover, the BCM5691 supports a fully-integrated data and address memory. The BCM5691 switch supports an I2C controller for communicating with external devices such as serial EEPROM, flash memories, and parallel port devices. The modular switching architecture of the BCM5691 embodies the scalability, integration and performance features that a next generation switch requires.
