... BCM567x/BCM569x Another prevalent system challenge is to minimize design, assembly, and manufacturing costs. Methods for lowering total costs are by constructing a switch using a minimum number of components, reusing chip resources and development expertise, and using a simple board assembly. And what about system features? To satisfy end customer requirements, switch makers must consider including most, if not all, of the following capabilities in their products: • ...

... BCM567x/BCM569x S XGS P F TRATA RODUCT The two primary chip components of the Broadcom StrataXGS Gigabit Ethernet switch architecture are the StrataXGS BCM5670 and the StrataXGS BCM5690. The BCM5670 is a high-speed (160-Gbps) switch fabric, also called a backplane or interconnect, that has eight 10-Gbps ports. A smaller version, the BCM5671 80-Gbps switch fabric with four 10-Gbps ports ...

The other primary StrataXGS component, the BCM5690 switch-on-a-chip. It supports twelve 1-Gbps ports and a one HiGig (10-Gbps) interface. The BCM5690 can be used in a standalone fashion to build a fixed 12-port switch can ...
Page 12
... BCM567x/BCM569x Another product, the BCM5691, supports 12 GE ports but no uplink, for use in standalone configurations. Both the BCM5690 and BCM5691 support a standard PCI bus for moving signals to and from the CPU and, in the case of the BCM5690 PCI uplink. StrataXGS chips are highly programmable, in that system designers can add value and differentiate their companies’ ...

... BCM567x/BCM569x BCM5690 Matrix. This type of interconnect is typically used for chassis-based systems and higher-end fixed systems. In this configuration, switching components are one hop away from the central processor that controls all the switches. Here, a switching fabric (BCM5670 or 5671) serves as a backplane to multiple BCM5690s that are connected to it. For resiliency, a matrix-based system can be configured with a redundant central processor, with switching chips interconnected to both processors in a full-mesh configuration ...

These characteristics are most appropriate for wiring closets in enterprise organizations where growth is expected or unpredictable. Each daisy chain-connected switch is typically built using BCM5670s with multiple BCM5690s connected to them. BCM5671 BCM5690 ...

... BCM567x/BCM569x THER YSTEM ESIGN In addition to deciding among the various types of component interconnects, other decisions must be made for each type of switch to be developed. The primary ones are outlined below IXED YSTEMS The designer needs to make design choices if the system is to have more than 12 ports. If there are 12 or fewer ports in the system, the designer can simply use a BCM5691 as a standalone switch ...

... BCM567x/BCM569x R /R ESILIENCY EDUNDANCY AT THE Enterprise customers are requiring near-100% uptime in their network equipment now, as data applications grow increasingly mission-critical and voice traffic (for which businesses have virtually no tolerance for downtime) joins the LAN. There are several ways that the StrataXGS architecture addresses this requirement. First, the BCM5670 has a redundant link so that system vendors can connect different ports across multiple paths ...

... BCM567x/BCM569x NTEGRATED ER ES NTERFACE The integration of a high-speed XAUI-compatible SerDes interface on each port reduces the complexity of board layout, because it eliminates the need for a component to connect to an external SerDes chip. The SerDes interface connects to both copper and fiber media. On StrataXGS 1-Gbps ports, SerDes runs at 1-Gbps. On StrataXGS 10-Gbps ports, four serial channels, each running at 3 ...
