Qualcomm QCC5171 - Bluetooth Audio SoC - QCC-5171-0-WLNSP99-TR-040

The Qualcomm QCC5171 - Bluetooth Audio SoC (MPN:QCC-5171-0-WLNSP99-TR-040) is a top-of-the-line, single-chip audio platform with ultra-low power consumption and programmable DSP optimized for use in true wireless earphones and hearing aids. Designed for the future of wireless sound, the Qualcomm® QCC5171 supports LE audio use cases and CD-less audio (16-bit 44.1 kHz) with Snapdragon Sound™ technology - our optimized chain of superior audio, connectivity and mobile innovations.

Built-in features include third-generation Qualcomm® Adaptive Active Noise Cancellation (ANC) with full-band ambient mode for powerful, effective noise cancellation and a natural sense of spatial awareness. 

With Qualcomm® aptX Adaptive Audio and high-performance DACs, the platform is designed to deliver high-resolution (24-bit 96kHz), low-latency audio through the Bluetooth audio processing chain. This dual-mode platform offers LE audio use cases for audio sharing, gaming, and stereo recording supported alongside traditional Bluetooth technology, providing an optimal listening experience in a variety of environments.

As consumer demand for smaller form factor devices continues to grow, the QCC5171 WLCSP case is designed to help manufacturers create ultra-small earphones that are comfortable enough to wear for extended periods of time.

Special Features

Special feature of the Qualcomm® QCC5171:

Integrated LE Audio and Classic Bluetooth audio
QCC5171 is qualified for a range of LE Audio-enabled use cases for earbuds, including audio sharing and broadcast, gaming mode and stereo recording. These dual-mode platforms integrate the best of LE Audio and the best of classic Bluetooth, to enable smooth feature adoption for real-world listening scenarios.

Excellence in audio
QCC5171 is designed to offer a selection of options for delivering crystal-clear voice calls in earbuds. These include super wide band voice quality with aptX Voice technology, and up to 3-microphone Qualcomm® cVc™ Echo Cancelling and Noise Suppression (ECNS).

This platform also supports both 24-bit 96kHz and 24-bit lossless audio quality in an adaptive platform, along with low-latency Bluetooth audio for gaming.

Integrated noise cancellation
QCC5171 supports our third-generation Qualcomm ANC, which leverages an integrated, dedicated hardware block on the platform. It supports incredibly low-latency and low-power performance for noise cancellation, without taxing the audio subsystem. This tech is designed for increased bit-depth and sample rates, allowing more precise filter control so audio developers can tune for stronger noise cancellation across a wider range of frequencies.

Concurrent support for differentiating audio features
Differentiate at a range of consumer price points with concurrent support for our portfolio of licensable audio technologies , including Snapdragon Sound, digital assistants, Qualcomm ANC, aptX Adaptive Audio, aptX Voice technology, cVc. QCC5171 is designed to support wireless earbuds, stereo headsets and speakers with the audio features consumers need most, and to seamlessly shift between them.
