BCM56770A0KFSBG

Overview

The BCM56770A0KFSBG is an Ethernet switch integrated circuit manufactured by Broadcom Limited. It belongs to the StrataXGS family of communication and networking ICs. The device provides a switching capacity of 2.0 terabits per second (Tbps). It supports 20 ports operating at 100 Gigabit Ethernet (100GE) speeds. The component is classified under ethernet switches within the broader category of ethernet ICs. It is distributed under the Broadcom/Avago trademark. The product complies with RoHS standards. The standard factory packaging quantity for this specific part number is 84 units.

Feature Summary

• Provides high-capacity switching fabric suitable for core network infrastructure
• Supports dense 100 Gigabit Ethernet port configurations
• Integrates advanced multilayer switching capabilities

Applications

• High-density data center interconnects
• Core router and switch platforms
• Enterprise network backbone aggregation

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure compatibility with required temperature ranges and package variants. Confirm that the 84-unit factory pack aligns with assembly requirements. Check for any recent Product Change Notifications (PCNs) that may affect material composition or pin definitions before finalizing procurement orders.

Selection Notes

Select this component when a 2.0 Tbps switching capacity is required with a fixed configuration of twenty 100GE ports. Ensure the system design accommodates the thermal dissipation needs of a high-performance Ethernet switch IC. Verify that the host board layout supports the specific FCBGA package footprint and signal integrity requirements for 100G SerDes interfaces.

Part Context

This model is part of the Broadcom StrataXGS portfolio, which targets high-performance switching applications. It sits alongside other models in the 567xx series, differentiated by throughput and port density. The BCM56770A0KFSBG specifically addresses the need for 100G uplinks in modern network architectures, preceding later generations that support higher aggregate bandwidths like 12.8 Tbps.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering changes within the same family may require re-verification of pinouts and software compatibility.
