TSCS42A1X1NLGXZAX

Overview

The TSCS42A1X1NLGXZAX is a low-power, high-fidelity integrated CODEC featuring 32-bit stereo playback and record functionality. It integrates a true cap-less headphone amplifier and a filterless DDX™ Class-D speaker driver delivering 3W per channel into 4Ω loads. The device supports sample rates from 8kHz to 96kHz with digital audio interfaces including I2S, Left-Justified, Right-Justified, and Bluetooth PCM modes. Key electrical specifications include 124dB SNR for DACs and 90dB SNR for ADCs. Power management allows operation with a 1.8V digital supply and a 1.7V analog supply.

Feature Summary

• Integrated Audio Output Processing (AOP) DSP engine providing tunable effects such as 3D stereo enhancement, parametric equalizers, and dynamic range compression via the Tempo ASC GUI.
• Filterless DDX™ Class-D speaker driver architecture that reduces bill of materials cost while maintaining high efficiency and low EMI through spread spectrum support.
• On-chip true cap-less stereo headphone driver utilizing charge-pump technology for ground-centered outputs, eliminating external coupling capacitors.
• Flexible digital audio interface supporting master or slave modes with adjustable frame lengths and selectable word lengths of 16, 24, or 32 bits.

Applications

• Bluetooth and Wi-Fi speakers
• Portable navigation devices
• Multimedia handsets and tablets
• Personal media players

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the component matches the exact part number required for the design to avoid pinout discrepancies between similar series variants.

Selection Notes

Select this component for designs requiring integrated DSP-based audio processing alongside power-efficient amplification. The device is suitable for battery-operated systems due to its low standby power consumption and flexible voltage requirements. Verify that the host processor supports the required digital audio interface formats and I2C control protocol.

Part Context

This model belongs to the TSCS42xx family of portable consumer codecs manufactured by Tempo Semiconductor. The family shares common architectural features but varies in pin configurations and specific output capabilities. The TSCS42A1 variant specifically denotes the pinout configuration for the 48-lead QFN package.

Replacement Considerations

Direct substitutes within the same family include the TSCS42A2X1NLGXZAX. Verify pin compatibility and feature parity before substitution, as differences may exist in GPIO assignments or specific amplifier configurations between the A1 and A2 variants.

FAQ

What is the maximum output power of the integrated speaker driver?

The filterless DDX™ Class-D speaker driver delivers 3W per channel into a 4Ω load and 1.5W per channel into an 8Ω load.

Does the device support digital microphone inputs?

Yes, the TSCS42A1 includes support for one stereo digital microphone (DMIC) input.

How is the internal DSP engine configured?

The Audio Output Processing (AOP) DSP engine is tuned using the Windows-based Tempo ASC GUI software, allowing designers to adjust parameters for equalization, compression, and spatial effects.
