BCM56720

Description

The BCM56720 is designed to enable next-generation modular and stackable Ethernet switching systems based on Broadcom's industry-leading StrataXGS® family of switches. The features, integration and low cost of the BCM56720 set a new standard in switch fabric design, and enable systems vendors to build scalable, cost-effective, next-generation switching systems.

The high-level of integration dramatically reduces the design complexity and power consumption of modular chassis systems. The BCM56720 integrates all the serializer/deserializer (SerDes) circuitry associated with all 16 fabric ports. Each SerDEs interface is CX-4 and can directly drive 16 Gbps of data across InfiniBand® cable or chassis backplane. The BCM56720 provides wirespeed switching performance across all ports simultaneously. Each HiGig+™/ HigGig2™ interface can run at 16 Gbps full-duplex, resulting in 256 Gbps of full-duplex switching bandwidth. The BCM56720 switch fabric design provides a solution that is cost-effective in small chassis configurations and can scale to multiterabit operation using multiple switch fabric stages.
