Product description

The Qualcomm QCC-3034-0-CSP90-MT-00-0 is a highly versatile and efficient Bluetooth audio SoC that provides a comprehensive set of features tailored to wireless audio devices, including TWS earbuds, stereo headsets, and wireless over-ear headphones. As a part of Qualcomm’s QCC30xx series, the QCC3034 focuses on delivering high-performance audio in mid-range to premium wireless audio products.


At the core of the QCC3034 is Qualcomm’s aptX codec, which is designed to provide high-quality Bluetooth audio. The aptX codec compresses and transmits audio without sacrificing sound quality, offering near-CD-level sound while reducing latency.


The QCC3034 also includes Bluetooth 5.0, which brings multiple advantages over previous versions of Bluetooth. With faster pairing times, extended range, and improved connection reliability, Bluetooth 5.0 ensures that devices using the QCC3034 will offer a more stable and efficient wireless experience


For voice communication, the QCC3034 integrates Qualcomm Clear Voice Capture (CVC) technology, which enhances voice clarity by reducing background noise and echo. This feature ensures that voice calls remain clear and intelligible, even in noisy environments like crowded streets or busy offices. 


The compact CSP90 package of the QCC3034 allows it to fit into small, lightweight devices, making it an ideal solution for manufacturers who want to design sleek, portable wireless audio products.
