Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QCC3020 chip is a Qualcomm generation low power TWS Bluetooth 5.1 chip, the important feature of the chip is to support the use of two analog or digital microphones at the same time for background noise reduction processing during calls, the chip uses Qualcomm's 8th generation CVC noise reduction technology.

The QCC3020 is packaged in a VFBGA package, with low manufacturing costs and a slightly larger size, and is targeted at general in-ear headphones and headphones. The chip is inexpensive, and mass production does not have high requirements for PCB boards and production lines.

Application scenario: mainly used for HFP calls, i.e. the usual phone call function, the main microphone captures the sound of the user speaking. The secondary microphone is used to capture background noise, such as wind, cars, distant speech, etc. The CVC technology eliminates the noise captured by the secondary microphone through internal software algorithms, leaving only the user's speech. This allows the other party on the call to clearly hear the person speaking, making the call sound full, clear and distance-free, and enhancing the user's sense of well-being.
