Overview
The BCM56260B0KFSBG is an Ethernet IC belonging to the Broadcom StrataXGS Saber2 series. It functions as a Layer 3 switch ASIC designed for high-performance data center networking applications. The component supports flexible port configurations including 100GbE, 40/50GbE, and 25GbE interfaces. Key technical specifications include a switching capacity of 3.2 Tbps and integrated SerDes capabilities. The device features hardware acceleration for network virtualization protocols such as VXLAN and NVGRE, along with support for RoCE and telemetry functions.
Feature Summary
- Hardware-accelerated overlay tunneling for VXLAN, NVGRE, and MPLS
- Integrated BroadView telemetry for flow statistics and congestion detection
- Smart-Buffer technology for dynamic packet buffering and load balancing
Applications
- Data Center Top-of-Rack (ToR) switches
- Leaf-Spine network architectures
- Blade server connectivity solutions
Procurement Notes
Verify the specific silicon revision indicated by the B0 suffix against your design requirements. Confirm that the KF package dimensions align with your PCB layout constraints. Ensure compatibility with the required SDK version for intended protocol support. Validate supply chain authenticity through authorized channels only.
Selection Notes
Select this component for designs requiring 3.2 Tbps throughput with native 25G SerDes integration. Consider the large FBGA package size during mechanical design. Evaluate thermal management needs due to high-density I/O. Verify software ecosystem support for OpenFlow or proprietary NOS implementations.
Part Context
This part belongs to the Broadcom StrataXGS Tomahawk generation family. It serves as a foundational building block for enterprise-grade switching infrastructure. The model represents a specific silicon stepping within the broader BCM56960 product line, optimized for high-port-density deployments in modern cloud environments.
Replacement Considerations
Direct substitutes are not publicly confirmed. Compatible alternatives may include later-generation Broadcom ASICs such as the BCM56990 series, though architectural differences require full system redesign.
