CS495303-CVZ

Digital Signal Processor Dsp Overview

The CS495303-CVZ is a 32-bit audio decoder DSP from the Cirrus Logic CS4953xx family, featuring dual Coyote 32-bit DSP engines operating at 150 MHz. It integrates on-chip ROM containing mainstream audio processing codes for Dolby Digital EX, DTS-ES, and THX Ultra2, eliminating the need for external SDRAM. The device supports up to 12 channels of 32-bit serial audio input and outputs 16 channels of PCM data with integrated S/PDIF transmission. It includes extensive post-processing capabilities such as tone control, parametric EQ, and bass management.

Digital Signal Processor Dsp Feature Summary

• Dual 32-bit Coyote DSP cores with 300 MIPS performance
• On-chip ROM for Dolby, DTS, and THX decoding without external memory
• Up to 12-channel digital audio input and 16-channel PCM output
• Integrated S/PDIF transmitter and flexible DMA controller

Digital Signal Processor Dsp Applications

• Audio decoders for home theater systems
• Digital broadcast receivers
• DVD/Blu-ray players
• Audio post-processors

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CVZ' against the manufacturer's official ordering guide, as datasheet documentation primarily lists 'DVZR', 'DQZ', and 'CQZ'. Confirm package availability, as the CS495303 is typically offered in 128-pin LQFP. Check current lifecycle status, as this component series may be discontinued or subject to limited supply.

Digital Signal Processor Dsp Selection Notes

Select the CS495303 over the CS49531x if lip-sync delay support exceeding standard requirements is not needed. Ensure the design utilizes the 128-pin LQFP package compatible with this model. Verify that the required third-party algorithms (e.g., Audyssey, SRS) are licensed for the CS4953x3 class firmware.

Digital Signal Processor Dsp Part Context

The CS495303 belongs to the CS4953xx enhanced DSP family, succeeding the CS495xx series. It is classified under ROM ID 3, distinguishing it from the CS4953x4 class which supports DSP Condenser applications. This family is designed for high-performance audio decoding with reduced system cost by minimizing external memory requirements.

Digital Signal Processor Dsp Replacement Considerations

The CS495313 serves as a functional superset within the same family, offering additional lip-sync delay features. For designs requiring DSP Condenser support, the CS495304 or CS495314 (ROM ID 4) are the recommended upgrades.
