BCM53347A0KFSBLG

Overview

The BCM53347A0KFSBLG is a smart switch IC manufactured by Broadcom Limited. It features an integrated architecture combining six QSFP+ ports and four 10GbE SFP+ ports. The device supports advanced Layer 2 switching capabilities, including VLAN tagging, QoS prioritization, and link aggregation. Designed for high-density connectivity, it integrates power management features such as Energy-Efficient Ethernet (EEE) to reduce idle power consumption. The component operates within commercial temperature ranges and utilizes a lead-free RoHS-compliant package suitable for enterprise networking infrastructure.

Feature Summary

• Integrates six QSFP+ and four 10GbE SFP+ interfaces for mixed-speed connectivity
• Supports Layer 2 switching functions including VLAN, QoS, and link aggregation
• Incorporates Energy-Efficient Ethernet (EEE) for reduced power consumption
• RoHS compliant with commercial temperature range operation

Applications

• Enterprise core and distribution layer switches
• Data center top-of-rack aggregation points
• High-performance network appliances requiring 10GbE uplinks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package type and temperature grade. Confirm RoHS compliance status with the supplier prior to purchase. Check for availability of engineering samples if initial prototyping is required. Ensure the supply chain source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a single-chip solution is needed for aggregating multiple 10GbE connections alongside higher-speed QSFP+ links. Evaluate thermal requirements against the commercial operating range. Compare pinout compatibility with existing PCB layouts designed for the BCM53347 family. Consider total system cost versus discrete PHY solutions for density requirements.

Part Context

This part belongs to the Broadcom BCM53347 series of smart switches. It shares architectural similarities with other members of the family but differs in port configuration and interface types. The series targets high-density switching applications requiring robust Layer 2 features and energy efficiency standards common in modern enterprise networks.

Replacement Considerations

Direct substitutes may include other BCM53347 variants with different port counts or interface types. Verify pin-to-pin compatibility before substitution. Cross-reference with Broadcom's official obsolescence notices for alternative recommendations.
