Overview
The BCM56640XB0KFSBG is a Broadcom StrataXGS Tomahawk series Layer 3 Ethernet switch ASIC designed for high-performance data center and carrier infrastructure. It delivers a switching capacity of 12.8 Tbps with integrated support for 25G, 40G, 50G, and 100G Ethernet interfaces. The device utilizes a large-pin-count FBGA package suitable for complex PCB layouts. Key technical features include FleXGS flow processing, Smart-Buffer memory management, and hardware offloading for overlay protocols such as VXLAN and NVGRE. It supports OpenFlow standards and provides telemetry capabilities via BroadView for network monitoring.
Feature Summary
- Supports flexible port configurations including 100G, 50G, 40G, and 25G Ethernet speeds.
- Integrates hardware acceleration for network virtualization overlays like VXLAN and MPLS.
- Provides programmable packet processing pipelines for advanced traffic handling.
Applications
- Data Center Top-of-Rack (ToR) switches
- Leaf-Spine network architectures
- High-density aggregation switches
Procurement Notes
Verify the specific silicon stepping and package revision against the required design specifications before procurement. Confirm RoHS compliance status and environmental ratings with the authorized distributor or manufacturer representative to ensure alignment with project requirements.
Selection Notes
Select this component for designs requiring 12.8 Tbps throughput with mixed-rate port flexibility. Ensure the PCB layout supports the necessary high-speed SerDes traces and power delivery for the FBGA package. Evaluate SDK compatibility for intended software-defined networking features.
Part Context
This part belongs to the Broadcom StrataXGS Tomahawk family, representing a generation of high-throughput switching solutions. It serves as a core component for building scalable network infrastructure capable of handling modern cloud and enterprise traffic patterns efficiently.
Replacement Considerations
Check for updated silicon revisions within the BCM56640 series. Consider next-generation Tomahawk models if higher bandwidth or lower power consumption is required for future-proofing the design.
