This scheme uses QCC3086 as audio transmitter and QCC3084 as Bluetooth receiver. The QCC3086 is a high-performance single-chip Bluetooth audio SoC platform that supports the latest Bluetooth 5.4 standard. The chip combines Snapdragon Sound and LE Audio technologies to deliver a low latency and high-quality audio experience. At the same time, the Auracast Bluetooth broadcast feature supported by the QCC3086 takes audio sharing to a new level, which allows users to enjoy high-quality audio without interference.
The QCC3083 also supports LE Audio and Auracast broadcast audio functions, which can be used as a Speak speaker or Headset to receive signals. The chip supports Qualcomm‘s Snapdragon Sound lossless, low latency and powerful music streaming technology to deliver superior listening experiences in complex environments. In addition, QCC3083‘s 24-bit 96KHz sampling frequency, I2S input/output interface, and support for Qualcomm CVC call noise reduction algorithm make QCC3083 particularly suitable for use in audio products.
