Digital Signal Processor Dsp Procurement Notes

Verify component status as the CS48L10-CNZR is listed as Not Recommended for New Design (NRND). Confirm availability through authorized distributors and check for recommended replacement options such as the CS48520 for new design implementations.

Digital Signal Processor Dsp Selection Notes

Select this part for cost-effective PCM processing where low power consumption is critical. Ensure the application requires support for MP3, WMA, or AAC decoding. Verify that the 80 MHz processing speed and 24-QFN package meet the system constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the CS48Lxx family of ultra-low power voice and audio DSP subsystems. It is derived from the CS485xx series but targets smaller form factors and lower power budgets. The CNZ suffix indicates the 24-QFN package variant operating at 80 MHz with 1.0 V core voltage.

Digital Signal Processor Dsp Replacement Considerations

For new designs, consider the CS48520 as a recommended replacement. The CS48520 offers higher performance with a 150 MHz clock speed and supports more channels.
