Since the official PDF is restricted, the hardware community has mapped the CX31993 in USB-C dongles (like the Ugreen 50744 and CableCreation). The chip is usually a 3mm x 3mm QFN.
: Measurement data shows excellent linearity across the audible frequency range (20Hz–20kHz). cx31993 datasheet
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. Since the official PDF is restricted, the hardware
