Cx31993 Datasheet [2021] Info

It maintains a flat response from 20Hz to 80kHz, making it suitable for "Hi-Res Audio" certification. 4. Pin Configuration and Integration

>128dB. This extremely high SNR indicates a very low noise floor, allowing for silent backgrounds in music. Dynamic Range (DNR): >120dB.

The chip is typically housed in a compact, low-profile QFN (Quad Flat No-Lead) package optimized for space-constrained cable assemblies. Functional Blocks

: Plug-and-play compatibility with Android , iOS (USB-C iPads/iPhones) , Windows 10/11 , and macOS . cx31993 datasheet

However, for developers focusing on the AFE version for sensor interfacing, the datasheet mandates a strict initialization sequence to ensure reliable operation:

The chip features excellent channel separation (typ. -110dB), ensuring a wide and accurate soundstage where instruments are clearly placed.

One of the CX31993’s standout features is its power efficiency. It is designed to draw minimal current from the host device (phone or tablet), which is critical for preserving battery life during long listening sessions. 3. Audio Performance Metrics It maintains a flat response from 20Hz to

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 reveals a highly capable DAC designed for modern, portable high-res audio. Its combination of high SNR, low THD, and strong driving power in a tiny USB-C package makes it an excellent choice for users looking to upgrade their mobile listening experience without spending a fortune.

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.

While full datasheets run dozens of pages, the headline features of the CX31993 usually include:

USB 2.0 Differential Data Plus and Data Minus lines. GND: System ground reference. Audio Output Group (DAC) HPOUT_L: Left channel headphone analog output. HPOUT_R: Right channel headphone analog output.
