QCC3086 combines classic Bluetooth and LE Audio to create a high-quality wireless audio experience
As wireless audio technology continues to evolve, Qualcomm QCC3086 chip has become a key force in promoting the development of wireless audio with its excellent performance and support for LE Audio technology. The Feitong FSC-BT1114QI Bluetooth module equipped with this chip integrates classic audio with emerging technologies, showing many advantages and becoming a potential choice in the wireless audio field.
1. LE Audio makes sound quality, power consumption and delay more coordinated
LE Audio is based on the Bluetooth Low Energy (BLE) architecture and is a comprehensive innovation rather than a simple upgrade. Its core advantage lies in achieving a triangular balance of sound quality, power consumption and delay:
Improved sound quality: Using LC3 encoder, the bit rate is significantly lower than traditional SBC encoding with the same sound quality. And it has strong anti-interference ability, which can reduce audio stuttering and disconnection even if the signal is weak, bringing a stable and high-quality experience.
Low-power design: Deeply optimized codecs and transmission protocols significantly reduce power consumption.
Low-latency transmission: LC3 encoding reduces latency and is suitable for scenarios that require high immediacy, such as games and live broadcasts. In the game, the sound and picture are synchronized to improve operation accuracy; in the live broadcast, the sound and picture are seamlessly connected, bringing a smooth audio-visual experience.
2. QCC3086 empowers FSC-BT1114QI to improve its characteristics
As the core of a high-performance wireless audio solution, Qualcomm QCC3086 chip has powerful processing capabilities and rich functional features. It supports the Bluetooth® v5.4 protocol and has excellent Bluetooth connection stability and low latency, providing a solid guarantee for audio transmission. At the same time, its built-in 240 MHz Qualcomm audio DSP provides powerful computing power support for audio processing. Whether it is dealing with complex audio encoding tasks or ensuring the smoothness of real-time audio transmission, it can be easily completed.
The FSC-BT1114QI Bluetooth module takes full advantage of the performance advantages of the QCC3086 chip. Adopting a compact 12mm × 17mm package, it is easy to integrate into various products. It has an onboard antenna and also supports external antennas to ensure signal transmission stability and coverage. The audio interface is equipped with a high-performance 24-bit stereo audio interface that supports digital and analog microphone input to meet diverse audio capture needs. In addition, it also provides flexible LED controller and PWM LED pins for convenient status indication and customized control.
3. Sound quality function reaches new heights
The QCC3086 chip's full support for LE Audio technology allows FSC-BT1114QI to achieve a significant improvement in sound quality and functionality. The support of LE isochronous channels (CIS/BIS/ISOAL) ensures the synchronization and stability of audio transmission. The application of LC3 encoding technology enables audio to maintain relatively good sound quality at lower bit rates, while effectively reducing power consumption. The addition of multiple streaming audio and Auracast broadcast audio functions provides users with a relatively rich audio sharing experience. Whether it is simultaneous playback of audio on multiple devices at a family gathering or audio broadcast in public places, FSC-BT1114QI can handle it well.
In terms of classic audio, this module supports synchronous connection-oriented channels (SCO: HFP) and asynchronous connectionless channels (ACL: A2DP), which can achieve relatively stable connections with existing Bluetooth headsets, speakers and other devices. And with the support of high-end audio algorithms, the sound quality performance can be improved to a certain extent, satisfying audio lovers’ pursuit of higher-quality music.
4. Multi-scenario application adaptation
FSC-BT1114QI has high compatibility, low latency and stable transmission characteristics, supports Bluetooth® v5.4 and LE Audio dual-mode operation, integrates core functions such as 24-bit audio processing and LC3 encoding, and is effectively used in the following fields:
Consumer electronics:
USB audio adapter: Adds Bluetooth functionality to computers and TVs, and achieves a more synchronized audio and video viewing and gaming experience through AptX Adaptive low-latency transmission.
Portable Bluetooth transmitter: Compact design, compatible with classic Bluetooth and LE Audio, can be connected to headphones and car systems to achieve convenient wireless audio conversion between devices.
Smart home:
Home theater system: Supports ISOAL packetization technology to achieve multi-channel lossless transmission, low latency, and effectively eliminate lip synchronization problems.
Multi-room simultaneous playback: Through the Auracast broadcast function, mobile phone and TV audio sources are synchronized to smart speakers throughout the house, supporting group control to meet diverse playback needs.
Professional equipment:
Fitness equipment: Integrate CIS isochronous channels to achieve efficient synchronization of audio and exercise data, and support heart rate monitoring voice prompts.
Professional recording: Utilizes 24-bit digital microphone interface and low-jitter clock to provide lossless transmission for wireless microphones and mixers, suitable for studios and live performance scenarios.
The combination of Qualcomm QCC3086 chip and Feitong FSC-BT1114QI Bluetooth module shows relatively outstanding advantages in the field of wireless audio. Whether you are pursuing high-quality sound quality, or focusing on the richness of functions and convenience of development, this combination can bring a relatively good experience to users. As wireless audio technology continues to develop, they are expected to continue to lead industry innovation and open up a more exciting audio world for users.
