BCM88270CA1KFSBG

Controllers Overview

The BCM88270CA1KFSBG is a high-performance Ethernet switch integrated circuit manufactured by Broadcom Limited. It provides a total switching capacity of 120 Gbps and features an integrated traffic manager and packet processor. The device supports multiple data rates including 1 Gb/s, 2.5 Gb/s, 10 Gb/s, and 40 Gb/s. It incorporates 28 transceivers for flexible port configurations. The component is designed for SMD/SMT installation and utilizes an FCBGA-896 package to accommodate the necessary pin count for enterprise networking applications.

Controllers Feature Summary

• Integrates traffic management and packet processing capabilities within a single chip architecture
• Supports multi-speed operation across 1G, 2.5G, 10G, and 40G Ethernet standards
• Provides 28 dedicated transceiver interfaces for versatile connectivity options

Controllers Applications

• Enterprise core and aggregation layer switches
• Data center top-of-rack (ToR) switching solutions
• High-density network infrastructure equipment

Controllers Procurement Notes

Verify the specific ordering suffix CA1KFSBG against the manufacturer's current datasheet to confirm package type and temperature range. Confirm RoHS compliance status with the supplier prior to order placement. Ensure the required factory packaging quantity aligns with production volume needs. Validate that the FCBGA-896 footprint matches the PCB design constraints.

Controllers Selection Notes

Select this component when a 120 Gbps switching fabric with integrated QoS and packet processing is required. Compare against other Broadcom Stratix series chips based on port density and buffer depth requirements. Ensure the design supports the thermal dissipation needs of the FCBGA-896 package. Verify compatibility with external memory interfaces if deep buffering is needed beyond internal caches.

Controllers Part Context

This part belongs to the Broadcom Ethernet IC portfolio, specifically categorized under communication and networking components. It is distinct from PHY-only solutions like the BCM54xx series or lower-capacity switches. The BCM88270 series targets high-throughput environments requiring centralized switching architectures rather than distributed processing models found in larger chassis systems.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering changes should be validated against the official Broadcom replacement matrix.
