Qualcomm Bluetooth audio SoC targets wireless earbuds, hearables

January 10, 2018 // By Jean-Pierre Joosting
Qualcomm Technologies International, Ltd., has introduced the QCC5100 series of Bluetooth 5.0 SoCs that are designed to help manufacturers develop a new generation of compact, feature-rich, wireless earbuds, hearables and headsets.

To meet demand for superior audio quality as well as extended battery life and playback time in wireless audio devices, the SoC series is engineered to reduce power consumption by up to 65 percent for both voice calls and music streaming, compared to previous single-chip Bluetooth audio solutions.

The SoC architecture supports low power performance and includes a Bluetooth 5 dual-mode radio, low power audio and application subsystems. Further, the platform supports advanced features including Qualcomm® TrueWireless Stereo, Qualcomm aptX HD audio, Integrated Hybrid Active Noise Cancellation (ANC) and third-party voice assistant services.

The QCC5100 series is designed to offer OEMs the freedom and flexibility to innovate, with a dedicated application processor sub-system, dual DSP architecture and next generation ADK software with enhanced development tools. The device family is also designed to support multiple use cases with concurrent software operation, meaning users can transition smoothly between functions including; listening to music, making calls, running biometric sensors and using voice assistant services

The platform features integrated hybrid ANC to help reduce the complexity and cost of adding ANC to earbuds, hearables and other portable audio devices by eliminating the need for a separate ANC chip. This helps manufacturers reduce the development time for premium audio experiences in much smaller form factor designs. Support for aptX and aptX HD audio technologies also helps to bring consistent, high-quality audio streaming over Bluetooth.

The QCC5100 series can help reduce development time and cost of voice activated products by combining local voice recognition algorithms running on the Bluetooth audio SoC with leading cloud services running on mobile applications.

Qualcomm TrueWireless Stereo technology is engineered to eliminate the need for wires entirely – not only between the media source and stereo headset, but also between left and right earbuds. The QCC5100 series is designed to deliver improved low power connectivity and enhanced user experiences for truly wireless in-ear applications.

Key features include:

  • Low power design and
