Codecs Procurement Notes

Verify current availability status as the component lifecycle indicates it is obsolete and scheduled for discontinuation. Confirm final time buy options if production continuation is required. Ensure compatibility with existing design specifications before procurement due to end-of-life status.

Codecs Selection Notes

Select this component only if legacy support for ISOModem interfaces is strictly required. Evaluate alternative modern codecs if new designs are permitted. Verify that the 16-bit resolution and 12 kHz conversion rate meet specific audio bandwidth requirements. Check package compatibility with existing PCB footprints.

Codecs Part Context

This part belongs to the Skyworks Solutions interface codec portfolio. It serves specialized niche markets requiring dedicated voiceband processing. The product line focuses on robust industrial and communication applications rather than consumer audio.

Codecs Replacement Considerations

No verified public substitute part numbers are available. Due to the obsolete status, direct replacements may require design modifications or adapter solutions.
