CS495314-CVZR

Digital Signal Processor Dsp Overview

The CS495314-CVZR is a 32-bit audio decoder DSP from the Cirrus Logic CS4953xx family, housed in a 128-pin LQFP package. It features dual Coyote 32-bit DSP engines (DSP A and DSP B) with a 150 MHz internal clock speed. The device supports up to 12 channels of 32-bit serial audio input and outputs 16 channels of 32-bit PCM data via two independent Digital Audio Output ports, each capable of functioning as a 192 kHz S/PDIF transmitter. It includes extensive on-chip memory for firmware and processing, supporting multi-standard decoding including Dolby Digital EX, DTS-ES, and AAC LC 5.1 without external SDRAM for core algorithms.

Digital Signal Processor Dsp Feature Summary

• Dual 32-bit Coyote DSP cores with 150 MHz internal clock for high-performance post-processing
• Supports up to 12-channel digital audio input and 16-channel PCM output with dual 192 kHz S/PDIF transmitters
• Integrated support for Dolby Digital EX, DTS-ES, THX Ultra2, and MPEG-2 AAC LC 5.1 decoding
• Includes DSP Condenser toolset for automatic boot/configuration from external serial FLASH

Digital Signal Processor Dsp Applications

• Multichannel audio decoders for home theater systems
• Digital broadcast receivers requiring lip-sync delay compensation
• Audio post-processing units with bass management and equalization
• DVD/Blu-ray players with advanced surround sound capabilities

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for any Product Change Notifications (PCNs) related to packaging or material changes. Ensure supply chain stability as availability may be limited depending on regional distribution agreements.

Digital Signal Processor Dsp Selection Notes

Select the CS495314-CVZR over the CS495304 variant when larger internal memory resources are required for complex post-processing algorithms or extended lip-sync delay buffers. The CS49531x series provides a superset of firmware features compared to the CS49530x series, including additional DTS formats and THX Ultra2 support. Ensure the design accommodates the 128-pin LQFP footprint and 3.3V I/O requirements.

Digital Signal Processor Dsp Part Context

The CS495314 belongs to the CS4953xx enhanced family, which improves upon the earlier CS495xx series with higher performance and lower system costs due to increased on-chip ROM. This family is designed for easy migration from previous generations with minimal hardware changes. The 'CVZR' suffix typically denotes the 128-pin LQFP package and specific tape-and-reel or cut-tape packaging options.

Digital Signal Processor Dsp Replacement Considerations

The CS495304-CVZR is a pin-compatible alternative within the same family but offers reduced internal memory and a subset of audio processing features. For designs requiring the full feature set of the CS49531x, no direct single-part replacement exists; consider evaluating the CS4970x series for newer architectures if available.
