TSCS42A1X1NLGIZAX

Overview

The TSCS42A1X1NLGIZAX is a low-power, high-fidelity integrated CODEC featuring 32-bit stereo playback and recording. It integrates a true cap-less headphone amplifier and a filterless DDX™ 3W stereo Class-D speaker driver. The device supports sample rates from 8kHz to 96kHz with stereo 32-bit DACs providing 124dB SNR and ADCs offering 90dB SNR. Digital audio ports support I2S, Left-Justified, Right-Justified, TDM, and direct Bluetooth PCM modes in master or slave configurations. It includes an on-chip Audio Output Processing DSP engine for effects like 3D enhancement and parametric equalization.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status directly with the manufacturer datasheet before procurement. Ensure the component meets humidity sensitivity requirements for your assembly process.

Selection Notes

Select this component for applications requiring integrated codec, headphone amp, and Class-D speaker driver functionality in a single package. Verify that the 48-lead QFN package fits the PCB layout constraints. Ensure the design supports the required 1.8V digital and 1.7V analog supply voltages.

Part Context

This part belongs to the TSCS42xx family of portable consumer codecs from Tempo Semiconductor. The family shares core DSP and audio processing capabilities but varies in pinout and specific output configurations. The TSCS42A1 variant specifically denotes the pin-compatible version within this series.

Replacement Considerations

Check the TSCS42A2 datasheet for pin compatibility if substituting within the same family. Verify that any alternative components match the 48-lead QFN footprint and support the required I2S/PCM interfaces.

FAQ

Does the TSCS42A1 support direct Bluetooth PCM mode?

Yes, the digital audio data ports support direct Bluetooth PCM mode in addition to standard I2S, Left-Justified, and Right-Justified formats.

What is the maximum supported sample rate?

The device supports sample rates ranging from 8kHz up to 96kHz.

How does the device manage electromagnetic interference (EMI) for the speaker driver?

It utilizes TSI Tri-State DDX™ Class-D technology which achieves low EMI via Spread Spectrum support while delivering high efficiency.
