R262 Datasheet, PDF (1/28 Pages) ON Semiconductor – Wideband Voice Capture and Noise Reduction Solution

BelaSigna R262
Wideband Voice Capture
and Noise Reduction
Solution
Introduction
BelaSigna^® R262 is a complete system−on−chip (SoC) solution that
provides wideband advanced noise reduction in voice capture
applications such as mobile phones, VoIP applications such as
webcams and tablet computers, two−way radios and other applications
that will benefit from improved voice clarity.
Featuring a novel approach to removing mechanical, stationary and
non−stationary noise, the chip preserves voice naturalness for greater
voice clarity and speech intelligibility even when the talker is further
away or not optimally aligned with the microphones providing
unmatched freedom of movement for end−users. Designed to be
compatible with a wide range of codecs, baseband chips and
microphones without the need for calibration, BelaSigna R262 is easy
to integrate, improving manufacturers’ speed to market.
Additional features include the ability to provide two
simultaneously processed outputs and to configure them depending on
the needs of a manufacturer’s device. The chip includes a highly
optimized DSP−based application controller with industry−leading
energy efficiency and is packaged in two highly compact 5.3 mm²
WLCSPs to fit into even the most sized−constrained architectures and
allows the use of common industry printed circuit board design
technologies.
Key Features and Benefits
