| BCM5692 (R) SCALABLE 12-PORT GIGABIT ETHERNET LAYER 2 SWITCH FEATURES * 12 10/100/1000-Mbps Ethernet ports supporting both copper and fiber connections * Integrated high-performance SerDes * Single 10-Gbps XAUI HiGig expansion port * Gigabit Ethernet SerDes per port * 4-pin per port SGMII interface to Gigabit Ethernet PHYs * 32 million packets/second (line-rate) aggregate switching capacity * 64 entries of FFP (Fast Filter ProcessorTM) SUMMARY OF BENEFITS * System vendors can build scalable high-performance, high port density Gigabit Ethernet LAN switches in several form factors. * 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 enable cost-effective and highperformance system design. * Scalable up to 32 BCM5692 switches in a system * Port trunking and mirroring supported across stacked switches * Fully integrated data and address memory on-chip * Full duplex (802.3x) compatible flow control TARGET APPLICATIONS * Layer 2 in modular Gigabit Ethernet switches * High port-count stand-alone or stackable Gigabit Ethernet layer 2 switches * Advanced diagnostic features including IEEE1149.1 JTAG boundary scan and BIST functionality * Low power * Enhanced thermal 480-pin EBGA package (pin-to-pin compatible with BCM5690/BCM5691) 10 Gbps HiGigTM Interface SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII PCI BSC IPIC GPIC GPIC GPIC GPIC GPIC GPIC CMIC L2 Table MMU VLAN Table GPIC GPIC GPIC GPIC GPIC GPIC CBP SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII SerDes/ SGMII 12-Port Gigabit Ethernet Multilayer Switch With HiGigTM OVERVIEW HiGigTM 10 Gbps XAUI Interface HiGigTM XAUI PCI 32/66 MHz CPU Interface HiGigTM CPU/IO ARL SRAM High-Speed On-chip Memory Packet Buffer MAC(s) Built-in SerDes with SGMII Support The BCM5692 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 BCM5692 supports both copper and fiber physical interfaces. The BCM5692 has a fully integrated SerDes functionality consisting of a 10-Gbps XAUI HiGig Port, Gigabit Ethernet, or SGMII PHY interface. The 10-Gbps HiGig Expansion port supports explicit priority, port trunking, and mirroring functions across switch elements. The HiGig port can be used to interconnect up to 32 BCM5692 devices, making it extremely useful for highly-scalable network switch applications. The BCM5692 has a built-in Fast Filter ProcessorTM that supports Layer 2-Layer 7 ContentAwareTM switching, packet filtering and network processing per port. The FFP has 64 entries. The BCM5692 supports advanced packet flow control such as head-ofline blocking prevention and IEEE 802.3x compatible full-duplex control. Moreover, the BCM5692 supports a fully- integrated data and address memory. The BCM5692 switch supports a BSC (Broadcom Serial Control bus) controller for communicating with external devices such as serial EEPROM, flash memories, and parallel port devices. The modular switching architecture of the BCM5692 embodies the scalability, integration, and performance features that a next-generation switch requires.
