The Qualcomm® QCC3086 is a single chip Bluetooth audio SoC platform designed specifically for USB dongles, optimized for gaming, video and enterprise applications.
QCC3086 is a single chip Bluetooth audio SoC platform designed to enable a rich set of features in a USB dongle form factor, bringing Snapdragon Sound™ Technology Suite to any source device. This solution broadens our Qualcomm S3 Gen 2 Sound Platform portfolio, delivering a dual-mode device qualified to Bluetooth 5.4, leveraging Classic Bluetooth and LE Audio, along with the features of Snapdragon Sound to source devices.
The QCC3086 combines Snapdragon Sound and LE Audio to deliver ultra-low latency of less than 20ms for lag-free wireless audio with voice back-channel for in-game chat. When delivering game audio only, the latency is further reduced. The QCC3086 also brings Snapdragon Sound support with Qualcomm® aptX™ Adaptive and aptX Voice, designed to enable music streaming at up to 24bit 96kHz and hands-free calling with Super Wide Band Voice.
Alternatively, OEMs can utilize the platform to add Auracast™ broadcast audio functionality to dongles and adapters for use with source devices such phones, laptops, TVs and a wide range of other audio equipment. Built for the emerging Bluetooth® LE Audio standard, the QCC3086 is designed to support Auracast™ Broadcast Audio and LE Audio Unicast for music and voice.
QCC3086 Highlights
Utilizing Snapdragon Sound and LE Audio to deliver ultra-low latency
We have a legacy of delivering industry leading low latency solutions and this solution takes advantage of Bluetooth® LE Audio combined with Snapdragon Sound to deliver ultra-low latency of less than 20ms for lag-free wireless audio with voice back-channel for in-game chat. When delivering game audio only, the latency is further reduced. Designed for use cases where low latency between earbud/headset is paramount for an immersive user experience, including gaming and video applications.
Dynamic Adaptation for robust connectivity and range
This solution is end-to-end optimized with Snapdragon Sound to ensure robust connectivity, the latency dynamically adapts based on the RF environment to ensure a seamless sound experience with no interruptions to the audio. For example, when gaming, users can walk away from the console and still hear all the gaming action and participate in game chat.
Bring Snapdragon Sound to any source device
The QCC3086 is optimized for use in USB dongle and earbud charging cases and will allow users to bringing the benefits of Snapdragon Sound to gaming with ultra-low latency, music streaming with 24-bit 96k support and hands-free calling with Super Wide Band support to any source device including TVs, laptops, gaming consoles, PCs, Hi-Fis and mobile phones.
