Conexant Brings Active Noise Cancellation and Ambient Inclusion to USB-C Headsets

Industry's First Single-Chip USB-C Solution Enables New Class of Features for Smartphone, PC and Gaming Headsets

SHANGHAI, CHINA--(Marketwired - Jun 29, 2016) - Audio and imaging innovation leader Conexant Systems, Inc. is on hand this week at Mobile World Congress Shanghai to highlight their new line of AudioSmart™ USB-C solutions that change what is possible for audio accessories. Conexant's highly efficient, powerful silicon and software solutions redefine the audio experience for a range of audio accessories including headsets, docking stations, smart home appliances, IoT solutions, automotive products, and more. Today, Conexant is showcasing its new CX20888 -- an Audio Stereo CODEC that is the first single-chip solution to allow USB-C-compliant active noise cancellation (ANC) and ambient noise inclusion in headsets.

USB-C is revolutionizing the interface market, enabling higher data speeds, faster charging, increased device interoperability and more -- all in a single cable. Billions of consumer devices are expected to take advantage of all that USB-C offers over the next few years, making it poised to become the connector standard of choice. USB-C's arrival on the scene has already had an impact on audio accessories, such as headsets, enabling a better, more powerful connection -- and removing the design limitations of the past.

Conexant continues to break new ground in the audio accessories field and is enhancing its AudioSmart family of USB-C-compliant audio CODECs with innovative new features. The CX20888 is the only single-chip solution that includes ANC, ambient inclusion and a 'Wake-On-Voice' trigger. This unique combination of features allows Conexant to offer the ultimate solution for USB-C headsets used in mobile, gaming and office environments. Conexant's ANC technology provides an impressive noise cancellation depth of up to 30dB with a range of up to 3.8kHz.

"With USB-C continuing to gain adoption at an unprecedented pace, we are seeing a truly new 'audio playground' emerge, where the possibilities for audio accessories are nearly limitless," said Saleel Awsare, Conexant president. "Our new stereo USB-C audio CODECs provide an open platform that gives developers the option to include more features than ever. Our ANC solution has shown superior performance without the suction effect you feel with competing solutions. Additionally, from motion and sensor connectivity to custom tuning profiles, we are providing an all-inclusive solution that opens the door to creativity and differentiation."

Featuring a stereo 24-bit DAC and ADC for music and voice communication applications, the CX20888 supports sampling rates of up to 96kHz. It minimizes bill of material costs by eliminating the need for an external crystal and integrates a capless headphone driver that produces a full-range frequency. The highly integrated CX20888 is housed in a 5mm x 5mm BGA package which requires minimal PCB area -- making it ideal for USB headset and docking station designs.

Other features include:

  • Wake-On-Voice
  • Multi-button support
  • Multi-level control of Ambient Inclusion
  • Ultra-low power consumption
  • Fully compliant with Skype for Business enterprise requirements
  • SWB NR (Super-Wide-band Noise Reduction)
  • SVP (Voice pick up) via in-ear microphones
  • SWB AEC (Super-Wide-band Acoustic Echo Canceller)
  • Wind Noise Canceller

Other hearables, including health monitoring headsets, will be targeted for the AudioSmart 3.0 treatment -- and a greatly enhanced user experience -- in the near future.
