CS495314-DVZ

Overview

The CS495314-DVZ is a 32-bit audio decoder DSP from the CS4953xx family, featuring dual Coyote DSP cores operating at 150 MHz. It integrates extensive on-chip ROM containing mainstream audio processing codes for Dolby Digital EX, AAC, 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 provides 16 channels of 32-bit PCM output with dual 192 kHz S/PDIF transmitters. It includes two SPI/I2C control ports, an external memory interface for SDRAM and Serial Flash, and customer software security keys.

Feature Summary

• Dual-core 32-bit DSP architecture with integrated DMA engine for high-performance signal processing
• On-chip ROM stores comprehensive audio decoding and post-processing algorithms without external code storage
• Supports lip-sync delay up to 150 ms per channel for synchronized audio-video applications
• Includes DSP Condenser support for automatic booting and self-configuration from external serial FLASH

Applications

• Audio decoders for home theater systems
• Digital broadcast receivers
• DVD audio/video players
• Audio post-processors in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 128-pin LQFP specification. Ensure compatibility with system voltage requirements, specifically the 3.3 V I/O supply. Check for any specific firmware licensing requirements for third-party audio algorithms before integration.

Selection Notes

Select this model when advanced lip-sync capabilities and dual-core processing are required. The CS49531x series offers a superset of features compared to the CS49530x, including additional DTS formats and larger internal memory. Consider the CS4953x4 class for designs requiring DSP Condenser support and simplified boot configurations via external serial flash.

Part Context

The CS495314-DVZ belongs to the CS4953xx enhanced DSP family, succeeding the earlier CS495xx series. It is part of the CS4953x4 class (ROM ID 4), which uniquely supports the DSP Condenser application for streamlined system integration. This family is designed to offer higher performance and lower system costs by minimizing external memory dependencies for standard audio codecs.

Replacement Considerations

CS495314-CVZR is a confirmed substitute within the same product family.
