The Conexant is a high-performance, low-power USB Type-C audio codec designed for mobile and portable audio applications . It has become a staple in the "audiophile dongle" market due to its ability to deliver high-resolution audio decoding in an incredibly compact form factor. Technical Specifications Overview
The is a highly integrated, low-power audio codec from Conexant (now part of Synaptics). It is designed primarily for USB Type-C wired headsets and dongles, enabling high-resolution audio playback and voice capture through a single connector. It is widely recognized in the consumer electronics market for offering superior audio quality compared to basic passive USB-C analog dongles.
Understanding the CX31993: High-Fidelity Audio in a Tiny Package cx31993 datasheet
For manufacturers, the CX31993 offers a well-understood, proven platform with simplified implementation requirements (no external crystal, minimal passive components, driverless operation) and flexible amplifier pairing options.
On Windows 11, some users have reported that high sample rates (384kHz) might conflict with certain "Spatial Audio" settings, requiring a bit of manual toggling in the sound control panel [12]. 🏆 The Verdict The Conexant is a high-performance, low-power USB Type-C
:
The full public datasheet for CX31993 is proprietary and not freely available. This guide is based on publicly disclosed specifications, application notes, and reverse-engineering from known products (e.g., Conexant/CX-Audio dongles). For register-level details, you must sign an NDA with the manufacturer. It is designed primarily for USB Type-C wired
Utilizes a charge-pump architecture to create a negative voltage rail internally. This allows the audio output to be biased at exactly 0V, removing the need for bulky, sound-degrading DC-blocking capacitors on the headphone outputs. 6. Hardware Implementation & Reference Design Guidelines
