21ic News ON Semiconductor has introduced a new system-on-chip (SoC) solution, BelaSigna® R262. The device offers broadband single-microphone or dual-microphone noise reduction for a variety of voice-capturing devices such as VoIP applications such as cell phones, webcams and tablets, and two-way intercoms.

BelaSigna® R262 offers a complete hardware and software solution with built-in voice capture and noise reduction technology that is extremely effective in dealing with both static and non-static background noise and mechanical noise. This provides greater speech intelligibility and comprehensibility, especially in extremely noisy environments. BelaSigna® R262 provides full 8 kilohertz (kHz) bandwidth for wideband voice capture for VoIP communications, eliminates reverberation, and supports 360° voice pickup, making it ideal for conference, mobile, and one-arm applications.
Advantages of BelaSigna® R262
· Easy to integrate: no special adjustments, calibration or use of external components
· Multi-capacity voice capture: consistent and effective voice capture regardless of the sound environment and the direction of use of the handheld device
· Flexible design: no restrictions on industrial design, providing a more free choice in microphone model and layout
The BelaSigna® R262 integrates a digital signal processor (DSP), voltage regulator, phase-locked loop (PLL), level shifter and memory in a tiny WLCSP package with a footprint of less than 6 square millimeters (mm2). The board space required is less than the competing solution that typically requires additional external components. This simplifies and speeds up the design process and helps engineers achieve the challenging goals of reducing design size.
Michel De Mey, senior director of portable audio products at ON Semiconductor, said: "BelaSigna® R262 is a unique off-the-shelf solution for communications equipment with extremely complex voice management design challenges. With customer expectations for speech intelligibility and noise management Increasingly, especially in the rapidly expanding VoIP market, it is especially important for designers to get technologies like ON Semiconductor's BelaSigna® R262 to help them design compelling communications devices that are available wherever and how they communicate. Clear voice."
