Cx31993 Datasheet ^new^ Online

It supports microphone input for calls and headset controls, which is frequently missing from more expensive, audio-only dongles. Summary of Technical Data Specification Chipset Conexant CX-Pro CX31993 SNR DNR THD+N Max Sample Rate 32Bit/384KHz DSD Support DSD 64/128 (PCM) Output Power Functions Audio + Mic + Controls Conclusion

The CX31993 chip was originally developed by , a prominent American semiconductor company acquired by Synaptics . While an open, consumer-facing PDF datasheet is rarely listed on standard public aggregate repositories, the technical parameters are derived from Synaptics' industrial product distributions, reference hardware designs (such as the CX-Pro and JCALLY series), and developer documentation. Key Technical Specifications

The CX31993 is recognized for delivering audiophile-grade performance within a standard bus-powered USB envelope. DAC Performance (Playback) 16-bit, 24-bit, 32-bit PCM Sampling Rates: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz, 384 kHz Signal-to-Noise Ratio (SNR): Up to 124 dB (A-weighted) Dynamic Range (DNR): 120 dB cx31993 datasheet

The CX31993 is a benchmark USB audio codec for cost-sensitive, high-performance consumer audio products. While not the absolute state-of-the-art (compared to ESS or AKM flagship DACs), its integrated USB controller, low power consumption, and excellent measured performance make it the de facto choice for sub-$15 USB-C audio dongles. Designers should obtain the full datasheet through Synaptics’ official distribution channels for exact register maps, thermal characteristics, and layout guidelines.
