CS42432-CMZ

Codecs Overview

The CS42432-CMZ is a high-performance audio codec featuring four 24-bit analog-to-digital converters and six 24-bit digital-to-analog converters. It supports differential or single-ended inputs and outputs within a 52-pin MQFP package. The device provides an ADC dynamic range of 105 dB (differential) and a DAC dynamic range of 108 dB (differential). Sampling rates reach up to 96 kHz for ADCs and 192 kHz for DACs. It operates with logic levels between 1.8 V and 5 V, utilizing a TDM serial interface and I²C/SPI control ports.

Codecs Feature Summary

• Integrates four multi-bit delta-sigma ADCs and six multi-bit delta-sigma DACs for high-fidelity audio processing.
• Supports industry-standard Time Division Multiplexed (TDM) serial interfaces alongside auxiliary PCM data input.
• Includes programmable digital volume control for all channels with selectable overflow detection capabilities.
• Features hardware mode configuration or software control via I²C and SPI protocols.

Codecs Applications

• A/V receivers
• DVD receivers
• Automotive audio systems

Codecs Procurement Notes

Verify the specific suffix 'CMZ' against the manufacturer's official ordering information to confirm the exact temperature grade and packaging specifications. Ensure that the required operating environment aligns with the commercial or automotive ratings defined in the datasheet before finalizing procurement.

Codecs Selection Notes

Select this component when designing systems requiring wide dynamic range and low distortion. Consider the 52-pin MQFP package constraints and verify compatibility with the host processor's TDM interface timing. Evaluate power supply requirements for the separate analog and digital rails to ensure stable operation across the specified voltage ranges.

Codecs Part Context

The CS42432 belongs to Cirrus Logic's high-definition audio codec family, designed for applications demanding negligible distortion and low noise. It serves as a central audio processing unit in complex multimedia systems, bridging analog front-end signals with digital back-end processing through its integrated oversampling modulators and filters.

Codecs Replacement Considerations

Consult the manufacturer's documentation for officially confirmed substitute part numbers. Verify pinout compatibility and functional equivalence before considering alternative components from other manufacturers.
