Procurement Notes

This component is officially discontinued and no longer manufactured by Broadcom Limited. Procurement involves significant risk as items are classified as non-cancelable and non-returnable. Buyers must verify current availability through authorized distributors, as stock levels fluctuate. Additionally, import tariffs may apply depending on the destination country, specifically regarding shipments to the United States. Due to its end-of-life status, sourcing should be approached with caution regarding long-term supply continuity.

Selection Notes

The BCM3228 is an obsolete component suitable only for legacy system maintenance or repair scenarios where original part replacement is mandatory. New designs should not utilize this part due to its discontinued manufacturing status. Engineers requiring active C-DOCSIS solutions must evaluate current Broadcom portfolios or alternative vendors offering supported lifecycle products. Verification of RoHS compliance indicates lead-free construction, but functional obsolescence remains the primary constraint for selection.

Part Context

Broadcom Limited provides semiconductors and infrastructure software for global organizations. The BCM3228 falls under their historical telecommunications portfolio, specifically targeting cable modem access networks. As a discontinued item, it represents older generation C-DOCSIS technology. Current Broadcom focus has shifted toward newer connectivity standards and AI infrastructure, rendering legacy telecom ICs like this one inactive in the main production line.

Replacement Considerations

No public confirmed substitute part numbers are available for the BCM3228. As a discontinued component, direct replacements are not officially documented by the manufacturer. Designers must consult third-party compatibility lists or redesign using modern C-DOCSIS controllers from active suppliers.
