The other primary StrataXGS component, the BCM5690, is a 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, or it can be
combined with other BCM5690s, BCM5670s, or StrataSwitch components to form different-sized configurations and to
achieve higher port densities. For example, eight BCM5690s can combine to scale from 12 to 96 GE ports.
Designers can link as many as 32 XGS chips (not including the switch fabric) for a maximum configuration of 384 GE ports
(ports using Broadcom components) and 64 (32 with BCM5673) 10-GE ports. One can also create a system containing 768
Fast Ethernet using X-StrataSwitch and Y-XGS components.
