CS47024C-CQZR

Digital Signal Processor Dsp Overview

The CS47024C-CQZR is a high-performance audio system-on-a-chip processor from the Cirrus Logic CS470xx family. It integrates a 32-bit DSP core with 300,000,000 MAC/S capability and dual MAC cycles per clock. The device features four channels of 24-bit ADC input (105dB dynamic range) and eight channels of 24-bit DAC output (108dB dynamic range). It includes integrated S/PDIF Rx/Tx, three hardware sample rate converters, and operates on a 1.8V core and 3.3V I/O supply. Packaged in a 100-pin LQFP with an exposed pad, it supports commercial temperature grades.

Digital Signal Processor Dsp Feature Summary

• 32-bit fixed-point DSP core with 300M MAC/S performance and 72-bit accumulators
• Integrated analog front-end: 4-channel 24-bit ADCs and 8-channel 24-bit DACs
• Built-in digital interfaces including 192 kHz S/PDIF Rx/Tx and configurable I2S/TDM ports
• Three internal hardware sample rate converter (SRC) blocks for multi-rate mixing

Digital Signal Processor Dsp Applications

• Automotive head units and outboard amplifiers
• Digital TV audio processing
• AVR and DVD receivers
• DSP-controlled speakers such as subwoofers and sound bars

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix CQZR against the manufacturer's current ordering guide to confirm package type and temperature grade. Confirm that the commercial temperature rating (0°C to +70°C) aligns with the target application environment requirements before finalizing procurement.

Digital Signal Processor Dsp Selection Notes

Select the CS47024 variant when the design requires four analog inputs and eight analog outputs. Ensure the host controller supports the required SPI or I2C serial control interface for boot configuration and runtime management. Verify that the 100-pin LQFP footprint matches the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the CS470xx series of audio processors, which are derived from the CS48500 family. It simplifies system design by integrating S/PDIF transceivers, analog I/O, and SRCs into a single chip, reducing overall component count compared to discrete solutions.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes within the same package include the CS47028C-CQZR and CS47048C-CQZR, which offer increased channel counts. Alternative packages such as the DQZ suffix variants exist but differ in temperature ratings.
