Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix CVZR against the manufacturer's current ordering guide to confirm package type (128-pin LQFP) and tape/reel specifications. Check for end-of-life status or alternative firmware versions as product information may evolve.

Digital Signal Processor Dsp Selection Notes

Select the CS495313 over the CS495303 for applications requiring DTS decoding, THX Ultra2 processing, and extended lip-sync delay capabilities. Ensure the design accommodates the 128-pin LQFP package and provides necessary 3.3V I/O and 1.8V core power supplies.

Digital Signal Processor Dsp Part Context

The CS4953xx family enhances the previous CS495xx series with higher performance and lower system costs by integrating more on-chip memory. The CS495313 represents the superset feature class within the x3 ROM ID group, offering advanced post-processing and decoding compared to the base CS495303 model.

Digital Signal Processor Dsp Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Migration from CS495xx requires minor hardware and software changes.
