QCC-5171-0-WLNSP99-SR-04-0

Overview

The DK-QCC5171-WLCSP99-A-0 is a development kit manufactured by Qualcomm, designed for the QCC5171 system-on-chip. It serves as an evaluation board for wireless and RF applications, specifically targeting premium tier occluded earbud reference designs. The kit includes left and right earbuds, ear interfaces in small, medium, and large sizes, a charger case, and a USB cable. It supports Qualcomm TrueWireless Mirroring with dynamic role swapping and single Bluetooth address management. The platform integrates third-generation Adaptive Hybrid Active Noise Cancellation (AANC) to provide high-quality immersive audio while allowing natural leak-through of ambient noise. It also supports Snapdragon Sound Technology and Qualcomm aptX Adaptive for low-latency, high-quality Bluetooth audio streaming at 24-bit/96kHz.

• Development of voice assistant-integrated hearable devices

Procurement Notes

Verify the exact part number DK-QCC5171-WLCSP99-A-0 against official Qualcomm documentation to ensure compatibility with the QCC5171 SoC. Confirm that the kit contents match the expected reference design components, including earbuds, interfaces, and charger. Check for any specific software build requirements for voice assistant integration directly from provider sources. Ensure compliance with RoHS3 standards and verify the manufacturer's standard delivery terms before ordering.

Selection Notes

Select this kit for developing premium true wireless stereo (TWS) earbuds requiring advanced noise cancellation and high-fidelity audio. It is suitable for engineers needing a pre-configured hardware platform to validate Qualcomm's TrueWireless Mirroring and aptX Adaptive technologies. Consider the inclusion of multiple ear interface sizes for ergonomic testing. This kit reduces development time by providing a complete reference design rather than individual components.

Part Context

This development kit is based on the Qualcomm QCC5171, a product of Qualcomm Technologies, Inc. It is categorized under RF, RFID, and Wireless Evaluation Boards. The kit is intended for use in the rapidly growing truly wireless earbud industry, helping manufacturers bring innovative features to market quickly. It supports the latest ADK features and is designed to reduce complexity and PCB space by integrating ANC functionality into a single-chip solution.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. The DK-QCC5171-WLCSP99-A-0 is a specific reference design kit for the QCC5171 SoC. Alternative development platforms would require separate sourcing of the SoC and custom board design, which does not offer the same out-of-the-box reference functionality.
