CS48560-CQZ

Digital Signal Processor Dsp Overview

The CS48560-CQZ is a high-performance 32-bit fixed-point digital signal processor (DSP) from the Cirrus Logic CS485xx family, designed for multichannel audio post-processing and mixing. It features a DSP core capable of 300 million MACs per second with dual MAC cycles per clock and 72-bit accumulators. The device supports up to 12-channel input and 12-channel output at sample rates up to 192 kHz. It includes an integrated S/PDIF transmitter, hardware-assisted sample rate conversion, and a PLL-based clock generator. Power supplies are 1.8V for the core and 3.3V for I/O, which is 5V tolerant. The component is housed in a 48-pin LQFP package.

Digital Signal Processor Dsp Feature Summary

• High-performance 32-bit DSP core delivering 300M MAC/s with dual MAC cycles and 72-bit accumulators
• Supports up to 12-channel PCM/DSD input and 12-channel output with sample rates up to 192 kHz
• Integrated S/PDIF transmitter and hardware-assisted sample rate conversion for mixed sampling frequencies
• Dual independent slave clock domains for input and configurable GPIOs with interrupt capabilities

Digital Signal Processor Dsp Applications

• Automotive head units and outboard amplifiers
• High-end digital televisions
• HD-DVD and Blu-ray Disc receivers
• Dual source/dual zone SACD systems

Digital Signal Processor Dsp Procurement Notes

Verify current availability status as the CS485xx family may be subject to end-of-life notices or production changes. Confirm that necessary third-party licenses for algorithms such as Dolby or SRS are secured prior to implementation. Ensure design compliance with the specific voltage levels and pin configurations outlined in the official datasheet.

Digital Signal Processor Dsp Selection Notes

Select the CS48560-CQZ when the application requires up to 12 channels of audio processing. This model offers higher channel counts compared to the CS48520 and CS48540 variants within the same family. Consider the internal ROM feature sets if custom firmware development is not required, or utilize the DSP Composer tool for custom processing chains.

Digital Signal Processor Dsp Part Context

The CS48560-CQZ belongs to the CS485xx family, which also includes the CS48520 and CS48540. These devices share the same 32-bit DSP core architecture and 48-pin QFP packaging but differ in input/output channel capacities and onboard memory allocation. The CS48560 represents the highest channel count option in this specific series.
