80-Gb/s Fabric Interface with Integrated Traffic Management

Currently Viewing:

The BCM88235 XGS Core® Fabric Interface with Integrated Traffic Management is part of the XGS Core Fabric family.
The BCM88235 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.
