CS497024-DVZ

Digital Signal Processor Dsp Overview

The CS497024-DVZ is a dual-core 32-bit high-definition audio decoder DSP from the CS4970x4 family, housed in a 128-pin LQFP package. It features two Coyote DSP cores (DSP A and DSP B) for simultaneous decoding and post-processing. The device supports major HD audio formats including Dolby Digital Plus, Dolby TrueHD, DTS-HD Master Audio, and DTS Express. It provides up to 12 channels of 32-bit serial audio input and outputs 16 channels of 32-bit PCM with dual 192 kHz S/PDIF transmitters. Operating conditions include a core supply of 1.8 V and I/O/PLL supply of 3.3 V.

Digital Signal Processor Dsp Feature Summary

• Dual-core architecture: DSP A handles HD audio decoding while DSP B manages post-processing and enhancement.
• Supports Dolby Digital Plus, Dolby TrueHD, DTS-HD Master Audio, DTS-HD High Resolution Audio, and DTS Express 5.1.
• Includes legacy format support such as Dolby Pro Logic IIz, DTS-ES, THX Ultra2, and SRS Circle Surround.
• Features 12-channel digital audio input (DAI) and two 8-channel digital audio output (DAO) ports supporting up to 192 kHz.
• Integrates external memory controller for SDRAM and Serial Flash, plus two SPI/I2C serial control ports.

Digital Signal Processor Dsp Applications

• Automotive head units and outboard amplifiers
• Digital TV and AV receivers
• DVD players and digital broadcast decoders
• DSP-controlled speakers and sound bars

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'DVZ' against the manufacturer's official ordering guide to confirm package type and temperature grade. As this is a specialized DSP component, ensure compatibility with required external SDRAM and boot configuration circuits before procurement.

Digital Signal Processor Dsp Selection Notes

Select the CS497024-DVZ when DTS-based HD audio formats are required alongside Dolby standards. Compare against the CS497014 if DTS support is unnecessary. Ensure design accommodates the 3.3 V I/O supply and 1.8 V core supply requirements, and verify that external SDRAM is included for TrueHD/DTS-HD processing.

Digital Signal Processor Dsp Part Context

The CS497024-DVZ belongs to the CS4970x4 family, an enhanced version of the CS4953xx series. It offers higher performance and additional HD audio decoding capabilities while maintaining software compatibility with existing CS495xx designs. The device simplifies system design by integrating S/PDIF Rx/Tx, analog interfaces, and sample rate converters into a single chip.

Digital Signal Processor Dsp Replacement Considerations

The CS497014-DVZ is a compatible alternative within the same family if DTS-format decoding is not required. Migration from CS495xx devices requires attention to PLL voltage differences (3.3 V vs 1.8 V) and the removal of external SRAM support.
