BCM88230 Functional Block Diagram
The BCM88230 XGS Core Fabric Interface with Integrated Traffic
Management is the latest member of the XGS Core Fabric family.
The BCM88230 integrates packet buffering, traffic management, and a
high-speed switch fabric interface. It provides four HiGig2 interfaces for
connection to packet processor devices, such as the BCM56620 family
of StrataXGS switch devices or the BCM88025 family of network
processors. These HiGig2 interfaces support channelized flow control.
The BCM88230 communicates with the BCM88130 fabric via fabric
SerDes that operates at up to 6.5625 Gbps.
The BCM88230 is used with the BCM88130 to create the total solution
of the XGS Core Fabric.
