delivers specs that rival far more expensive alternatives, boasting , high SNR, and a surprisingly clean, neutral sound profile. cx31993 datasheet
This is the section most visitors looking for the "CX31993 datasheet" care about. Here is the verified performance data based on OEM testing and reverse-engineered specifications.
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 It supports microphone input for calls and headset
The CX31993 is designed for high-fidelity audio playback. Its decoding capability ensures it can handle high-resolution audio files without downsampling, preserving all the original detail. The key to its "Hi-Fi" designation lies in its >128dB SNR , which means the audio signal is significantly louder than the background noise, resulting in an exceptionally clean and "black" background. This is further supported by a THD+N of less than 0.0003% , indicating extremely low distortion. While some community members note that the 1Vrms output may have higher distortion compared to certain alternatives, its overall noise floor remains very low.
Type-C to 3.5mm (commonly used in cables with 4-strand transparent silver and 4-strand blue mixed wire). 3. Compatibility and Functionality delivers specs that rival far more expensive alternatives,
Supports DSD 64/128 (PCM), allowing for Native DSD playback. 2. Output and Power
The CX31993 is superior to old Realtek ALC4042 chips (found in Google’s first dongle) but is technically beaten on sheer power by the ALC5686. However, the CX31993 has better noise immunity (124dB SNR), making it the king of black background silence.
By accessing the CX31993 datasheet, developers and engineers can gain a deeper understanding of this powerful IC and unlock its full potential in their designs. Whether you're working on a professional audio system, musical instrument, or audio equipment, the CX31993 is an excellent choice for high-performance audio processing.
