ON Semiconductor BelaSigna R262 wideband advanced noise reduction system-on-chip

ON Semiconductor BelaSigna R262 is a system-on-chip (SoC) solution that provides wideband single- or dual-microphone noise reduction in a diverse range of voice capture devices such as mobile phones, VoIP applications including webcams and tablet computers, and two-way radios.

BelaSigna R262 offers a complete hardware and software solution with built-in voice capture and noise reduction technology that is highly effective in managing stationary and non-stationary background and mechanical noise. This results in improved voice clarity and intelligibility, especially in demanding noisy environments. With full 8 kHz bandwidth wideband voice capture for VoIP communication, de-reverberation capability and 360° voice pick-up, the R262 is suitable for conference, handset and arm’s length applications.

It integrates a digital signal processor (DSP), voltage regulators, phase-locked loop (PLL), level translator and memory all within a small footprint WLCSP package of less than 6 mm², requiring less board space, which avoids the use of additional external components. This simplifies and accelerates the design process and helps engineers meet challenging design size-reduction objectives.

With ever-increasing customer expectations regarding voice clarity and noise management, particularly in the VoIP market, it is important that designers have access to complete hardware and software technology to support them in offering compelling products that do not place restrictions on how and where clear and intelligible communications can take place.
