Product Overview
The CS495313-CVZ is a high-performance 32-bit dual-core audio decoder DSP by Cirrus Logic for high-end consumer and automotive audio systems.
Its dual-core design separates multi-channel surround decoding (Dolby Digital, DTS, Dolby Pro Logic IIx) and custom acoustic post-processing to avoid audio latency.
On-chip preloaded ROM stores certified audio codecs, cutting external flash requirements. Built-in RAM/ROM simplifies firmware development, while the 128-LQFP lead-free package delivers stable, high-fidelity multi-channel audio output.
Core Advantages
Dual-Core 32-Bit Processing Architecture
Features independent dual-core computing engines optimized for high-fidelity audio, allowing simultaneous format decoding and custom post-processing virtualization without system audio latency or jitter.
Pre-programmed Certified Audio Codecs
Comes equipped with an on-chip ROM library pre-loaded with licensed Dolby Labs and DTS routines, eliminating the need for bulky external boot flash memories to load basic surround sound configurations.
Ultra-Precise Dynamic Range and Resolution
Utilizes a fixed-point 32-bit data path combined with a 72-bit accumulator matrix to preserve absolute signal integrity, preventing digital audio clipping during heavy transient equalizer configurations.
Comprehensive Multi-Channel I/O Routing
Supports flexible serial audio input and output configurations capable of routing multiple concurrent channels of PCM, S/PDIF, or compressed bitstream data smoothly into modern external DAC networks.

Frequently Asked Questions
Q1: Is your listed inventory of the CS495313-CVZ processor fully authentic and original?
A: Yes, we guarantee that all CS495313-CVZ audio DSPs in our warehouse inventory are 100% brand-new, factory-original products from Cirrus Logic, carefully stored and handled under strict anti-static ESD packaging guidelines.
Q2: What is the specific functional significance of the “Z” designator within the part number?
A: The “Z” suffix explicitly denotes that the component is packaged in a fully lead-free, green configuration, adhering strictly to global RoHS directives regarding environmentally hazardous substances.
Q3: Does the dual-core architecture mean we can implement our own custom post-processing software algorithms?
A: Yes, exactly. While the primary core handles the heavy algorithmic decoding of standard audio bitstreams using pre-programmed ROM codes, the secondary core is designed for custom code execution, allowing you to run your own custom filters and acoustic profiles.
Q4: How can our engineering group obtain the specialized software application code tools, firmware libraries, or request a volume discount quote?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
