Codecs Procurement Notes

Verify the component status as obsolete or end-of-life through official manufacturer channels before design finalization. Confirm that the specific ordering suffix matches the required package and temperature grade. Ensure all technical specifications align with current project requirements prior to procurement.

Codecs Selection Notes

Select this component for applications requiring wide dynamic range and negligible distortion. Verify compatibility with serial audio interface formats such as I2S, left-justified, and right-justified modes. Ensure the power supply voltage ranges meet the system's analog and digital supply requirements.

Codecs Part Context

This part belongs to the Cirrus Logic CS42518 family of high-performance audio codecs. It is designed for multi-channel audio processing with integrated digital interfaces. The CQZ suffix indicates the commercial temperature grade and the 64-pin LQFP package type.

Codecs Replacement Considerations

Consult the manufacturer's documentation for officially confirmed substitute part numbers. Verify pinout compatibility and functional equivalence before considering alternative components.
