资 源 简 介
BELASIGNA R261 is a complete system−on−chip （SoC） soluTIon that provides advanced dual−microphone noise reducTIon in voice capture applicaTIons such as laptops， mobile phones， webcams， tablet computers and other applicaTIons that will benefit from improved voice clarity.
BelaSigna R261 is designed to allow both digital and analog processing in a single system. Due to the mixed−signal nature of this system， careful design of the printed circuit board （PCB） layout is critical to maintain the high audio fidelity of BelaSigna R261. To avoid coupling noise into the audio signal path， keep the digital traces away from the analog traces. To avoid electrical feedback coupling， isolate the input traces from the output traces.
