Cx31993 Datasheet
To fully appreciate the CX31993 datasheet, one must compare it to the market alternatives.
| Feature | CX31993 | Realtek ALC5686 | Realtek ALC4042 | | :--- | :--- | :--- | :--- | | Max Sample Rate | 384 kHz | 384 kHz | 96 kHz | | SNR | 124 dB | 120 dB | 104 dB | | THD+N | -93 dB | -95 dB | -85 dB | | Output Power (32Ω) | 30 mW | 33 mW | 40 mW | | DSD Support | DSD128 | DSD128 | No | | Typical Use | Mid-range dongles | High-end dongles | Budget dongles |
Conclusion: 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.
For hardware engineers designing a device, choosing a codec is a balancing act between price, board real estate, and audio fidelity. The CX31993 is often selected for its integrated DSP (Digital Signal Processing) capabilities.
This allows developers to offload audio processing tasks—such as equalization, noise suppression for microphones, and 3D sound effects—from the main CPU to the codec itself. This not only frees up the CPU for other tasks but ensures consistent audio processing latency.
The CX31993 represents a tier of audio hardware that prioritizes clarity and power efficiency. While many modern phones are moving toward USB-C dongles and wireless audio, having a dedicated, high-quality codec like the CX31993 on-board is a hallmark of a device designed for the true music lover.
