Digital Signal Processor Dsp Procurement Notes
This component is officially obsolete as per Product Change Notification dated September 4, 2025. Manufacturers have ceased production, and inventory will not be replenished after existing stock is depleted. Verification of current availability should rely solely on distributor surplus listings, as no new units are being manufactured.
Digital Signal Processor Dsp Selection Notes
Designers must account for the obsolescence status when selecting this part. Since the CS48LV41-CWZR is no longer recommended for new designs, alternative components from the same manufacturer or compatible successors should be evaluated for long-term supply chain stability and technical compatibility.
Digital Signal Processor Dsp Part Context
The CS48LV41-CWZR belongs to the Cirrus Logic CS48LV41 family of embedded DSPs. It shares the base model identifier CS48LV41 but utilizes the CWZR suffix to denote its specific 20-WLP package type and commercial temperature rating. This distinguishes it from other variants in the series that may offer different packaging or extended temperature ranges.
Digital Signal Processor Dsp Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult Cirrus Logic's official transition guides or contact the manufacturer directly for validated replacement recommendations.
