Mara found it the night she couldn't sleep, finger tracing the silicon-era font of the table of contents. She worked as a hardware bring-up engineer at a small robotics startup, but lately the company had stalled on a stealthy, underwater glider project. The guts of the design had been outsourced years ago to a supplier who'd vanished when the venture faltered. Only one line in the bill of materials glowed with promise: CX31993 — a mixed-signal timing-and-control IC labeled “discontinued” but still mysterious. cx31993 datasheet
While not extensively documented, the CX31993's USB audio architecture provides , making it suitable for real-time applications such as:
The is a high-performance USB-C audio decoding chip designed by Conexant (now operating under the Synaptics brand) that has gained considerable acclaim in the portable audio market. This guide serves as a comprehensive resource for the CX31993, consolidating all available technical specifications, performance metrics, application notes, and design insights. While an official PDF datasheet from the manufacturer remains elusive—and some sources indicate that official technical documentation for this chip may have been discontinued—this article synthesizes the most reliable data from product implementations, technical analyses, and real-world measurements to provide a complete picture of this remarkable DAC chip. Consumes low power, making it excellent for mobile use
The CX31993 has been subjected to independent testing and measurement by various sources. The following data, taken from tests of the GraveAudio DA06 CX31993 device, illustrates the chip's real-world performance:
A: Yes. Despite the lack of official documentation, the CX31993 remains a highly competitive choice for entry-level to mid-range portable DAC products. Its proven track record, widespread adoption, excellent specifications, and low cost continue to make it attractive for volume manufacturing. However, for applications requiring DSD support, advanced filtering, or robust manufacturer support, alternative chips such as the Cirrus Logic CS43131 should be considered. The guts of the design had been outsourced
In practical use, the CX31993 is described by reviewers on AudioReviews.org as having a tonality with a clean, uncolored output. Any link to the cx31993 datasheet? - Facebook
The CX31993 chip was originally developed by , a prominent American semiconductor company acquired by Synaptics . While an open, consumer-facing PDF datasheet is rarely listed on standard public aggregate repositories, the technical parameters are derived from Synaptics' industrial product distributions, reference hardware designs (such as the CX-Pro and JCALLY series), and developer documentation.
