Cx31993 Datasheet [WORKING]

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.

Pins 13 & 14 are critical. The CX31993 requires a precise 24MHz crystal oscillator with ±50ppm tolerance. Using a ceramic resonator instead will cause jitter and sample rate mismatch.

The (within ±0.1dB) confirms that the CX31993-based devices are neutral and accurate, without introducing tonal coloration. The crosstalk figures indicate excellent channel separation, contributing to a wide and precise stereo image. cx31993 datasheet

The CX31993 is a USB audio codec specifically engineered for USB-C to 3.5mm audio adapters, portable DAC/amps (often called "dongles" or "小尾巴"), and other mobile Hi-Fi applications. Unlike many competing solutions, the CX31993 is designed with a singular focus: delivering high-quality analog audio output with extremely low power consumption, making it ideal for smartphone-powered audio upgrades.

Years later, when the startup had grown and the original glider had become a fleet, younger engineers would ask how they’d achieved such reliable timing with discontinued parts. Mara would hand them the framed page, point to her margin scribbles, and say, “Read it. Build what it tells you.” The reveals a highly capable DAC designed for

: It is noted for running cool and having minimal impact on a smartphone's battery life, often consuming only about 2% extra battery per hour of use.

in 2017, its technical capabilities and real-world performance are well-documented through enthusiast testing. Core Specifications (from Datasheet Data) Resolution: Supports up to 32-bit / 384kHz PCM. Output Power: Typically rated at 65mW @ 32Ω 1.0 Vrms output (superior to the 0.5V EU Apple dongle). Signal-to-Noise Ratio (SNR): Frequently cited at Dynamic Range (DNR): Distortion (THD+N): 0.0003% or ~95dB.

She started small. A breadboard, an old microcontroller, a handful of capacitors she scavenged from broken equipment. Late into the night, the CX31993’s oscillator hummed in translucent green on the scope, its timing edges neat as a metronome. The datasheet's “Absolute Maximum Ratings” page, which the less meticulous often ignored, had saved her a charred MOSFET and a migraine; its “Typical Operating Characteristics” page taught her patience. Each clause in the document folded into her routine—she measured propagation delay the way others measure coffee intake.
