ONSemi introduces BelaSigna R262 wideband advanced noise reduction system-on-chip

ON Semiconductor, a supplier of high performance silicon solutions, has introduced the BelaSigna R262, a new 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.

The 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 kilohertz (kHz) bandwidth wideband voice capture for VoIP communication, de-reverberation capability and 360-degree voice pick-up, BelaSigna R262 is ideal for conference, handset and arm’s length applications.

The BelaSigna R262 is easy to integrate – special tuning, calibration or external components are not required; offers versatile voice capture: it consistently captures voice regardless of acoustic environment or the orientation of the handheld device while in use and provides design flexibility: industrial design is unconstrained with greater freedom of choice on microphone model and placement.

The BelaSigna R262 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 square millimeters (mm)2, requiring less board space than significantly larger competing solutions that often require additional external components. This simplifies and accelerates the design process and helps engineers meet challenging design size-reduction objectives.

“BelaSigna R262 is a drop-in solution for communication devices that pose the most complex voice management design challenges,” said Michel De Mey, senior director portable audio products at ON Semiconductor. “With ever increasing customer expectations regarding voice clarity and noise management – particularly in the rapidly-expanding VoIP market – it is important that designers have access to technology like ON Semiconductor’s BelaSigna R262 to support them in offering compelling products that do not place restrictions on how and where clear and intelligible communications can take place.”
