CS4236B-JQ

Audio Special Purpose Overview

The CS4236B-JQ is a CrystalClear Audio Codec by Cirrus Logic Inc., designed for high-performance audio signal processing. It features a stereo architecture with two channels, supporting serial interfaces for data communication. The device operates within dual voltage supply ranges: 3V to 3.6V and 4.75V to 5.25V. It is rated for an extended operating temperature range of -55°C to +125°C (TA). Packaged in a 100-LQFP surface-mount case, specifically identified as a 100-TQFP (14x14) footprint, this component serves as a dedicated audio system processor.

Audio Special Purpose Feature Summary

• Stereo audio codec with two-channel signal processing capability
• Dual voltage supply support: 3V–3.6V and 4.75V–5.25V
• Extended industrial temperature rating from -55°C to +125°C
• Serial interface connectivity for digital audio data

Audio Special Purpose Applications

• General audio systems requiring high-fidelity signal processing
• Industrial audio equipment needing wide temperature tolerance
• Professional audio hardware utilizing serial digital interfaces

Audio Special Purpose Procurement Notes

Verify the specific package variant against the supplier description, which lists both 100-LQFP and 100-TQFP (14x14). Confirm that the required voltage rail matches either the 3V or 5V domain, as the device supports distinct ranges. Ensure the application environment stays within the specified -55°C to +125°C thermal limits for reliable operation.

Audio Special Purpose Selection Notes

Select this component when a stereo codec with serial interface is required for robust industrial or professional audio applications. The dual voltage option allows flexibility in power design. The wide temperature range makes it suitable for harsh environments where standard commercial grade parts would fail. Verify pin compatibility if replacing older versions due to potential package differences.

Audio Special Purpose Part Context

This part belongs to the Cirrus Logic CrystalClear Audio Codec family, known for high-quality analog-to-digital and digital-to-analog conversion. The CS4236B series typically targets high-end audio markets. The 'JQ' suffix likely denotes specific packaging or temperature grade variations within the broader product line, though exact suffix definitions require manufacturer documentation.

Audio Special Purpose Replacement Considerations

Direct substitutes should be sought from the Cirrus Logic CS4236B series or compatible stereo codecs with similar serial interfaces and voltage ranges. Verify pinout compatibility carefully, especially regarding the 100-pin package dimensions. Check if alternative parts meet the -55°C to +125°C temperature specification.
