Procurement Notes

This component is officially listed as End-of-Life (EOL) and no longer manufactured by Broadcom Limited. Availability is restricted to remaining stock from distributors or third-party suppliers. Buyers should verify authenticity and condition carefully, as new original units are limited. Non-cancelable and non-returnable terms may apply to existing inventory transactions. Due to its discontinued status, long-term supply continuity cannot be guaranteed through standard manufacturing channels.

Selection Notes

Select this part only if specific legacy compatibility or existing design constraints require the BCM5345X family architecture. Consider that it is discontinued; alternative newer generations from Broadcom may offer better availability and updated features. Evaluate whether the integrated 2MB buffer and mixed speed ports meet current throughput requirements without needing external memory or additional PHY components.

Part Context

The BCM5345KPBG is part of Broadcom’s broader BCM5345X device family, which provides scalable switching solutions. It serves as a controller within the communication and networking ICs subcategory. The package type is BGA, suitable for dense PCB layouts. It is marketed under the Broadcom / Avago trademark and functions primarily as a SERDES-based switch processor for high-density port configurations.

Replacement Considerations

As the BCM5345KPBG is End-of-Life, direct substitutes are not officially confirmed in public documentation. Designers should consult Broadcom’s current portfolio for next-generation SoC switches that maintain similar pinouts or functional equivalents. No specific replacement part numbers are verified in available sources.
