Digital Signal Processor Dsp Procurement Notes

The CS496122-CQZ is listed as an obsolete product by Cirrus Logic. Verification of current availability requires checking authorized distributors for remaining stock or surplus inventory. Designers should review the official End-of-Life (EOL) notification documents for discontinuance timelines and recommended replacement strategies before finalizing procurement plans.

Digital Signal Processor Dsp Selection Notes

Select the CS496122-CQZ when 16-channel CobraNet connectivity is required within a single integrated component. This part replaces discrete DSP and networking solutions, reducing board space and system costs. Ensure the application design accommodates the 144-pin LQFP footprint and utilizes the provided DSP Conductor software for firmware development and parameter adjustment.

Digital Signal Processor Dsp Part Context

This component belongs to the CS4961xx family of audio system processors, which also includes the CS496102 (2x2 channels) and CS496112 (8x8 channels). All variants share the same core architecture and CobraNet integration but differ in channel count. The CS496122 represents the highest capacity option in this specific series for professional audio networking.

Digital Signal Processor Dsp Replacement Considerations

No direct public substitute part numbers are documented for this discontinued model. Engineers must evaluate newer Cirrus Logic audio networking solutions or third-party alternatives based on pin compatibility and functional requirements.
