Cx31993 Datasheet

As the first track began to play, the "lean, neutral-to-slightly-bright" tonality the datasheet promised flooded her senses. The low-impedance IEMs in her ears didn't just play music; they reconstructed a lost reality. She could hear the distinct "air" between instruments, a transparency that the bulky, more expensive amplifiers of her era could never mimic.

: Usually 8-strand silver-plated copper for better durability and signal integrity.

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. cx31993 datasheet

The CX31993 is a highly integrated, low-power USB Type-C digital audio codec designed by Conexant (now part of Synaptics). It has become a dominant component in the portable audio market, specifically powering high-resolution USB-C to 3.5mm dongles, external DACs (Digital-to-Analog Converters), and inline headphone amplifiers.

| Limitation | Description | | :--- | :--- | | | Limited manufacturer-published technical documentation is available | | No Native DSD Support | Any DSD playback relies on software conversion (DoP) | | No ADC Functionality | Cannot be used for high-quality recording applications | | No Active Noise Cancellation (ANC) | Unlike its sibling CX21988, the CX31993 does not support ANC output | | Limited Advanced Filtering | Lacks the adjustable filters and gain settings of higher-end chips | | Discontinued Support | Some sources indicate official technical documentation for this chip may have been discontinued | | High-Impedance Limitations | Not designed for extremely power-hungry planar magnetic headphones | As the first track began to play, the

For engineers and product designers considering the CX31993 for their projects, the following implementation notes are essential:

Supports DSD 64/128 (PCM), allowing for Native DSD playback. 2. Output and Power It is widely recognized in the consumer electronics

: With a high SNR of 128dB, it provides a "black" background, which is essential for sensitive In-Ear Monitors (IEMs) that often pick up electrical noise from poorly shielded devices. Common Implementation: The "CX-Pro" Dongle While the is a chip, you will most commonly find it inside the CX-Pro DAC Dongle Go to product viewer dialog for this item. . These devices often feature:

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

The CX31993 datasheet provides detailed specifications for the IC, including:

While numbers tell part of the story, the actual "ear feel" is what matters. Community reviews from platforms like AudioReviews.org and various enthusiast forums describe the CX31993 sound as:
