Introduction

The V2S200D is a high bandwidth, low-power specialized vibration sensor which improves voice call quality in noisy environments and windy conditions. It offers over 50dB acoustic isolation in noisy environments (bars, airports, windy outdoor spaces). The PDM interface facilitates seamless integration on a PDM bus together with a traditional PDM microphone and its port-less package makes it robust to particles and liquid ingress. PDM microphones have an integrated ADC and return oversampled PDM data at the supplied clock frequency. Advantages of PDM microphones include superior noise immunity, simpler PCB layout, typically better system SNR and lower overall power consumption. PDM microphones can greatly simplify system design if the processor or CODEC supports a PDM port. MEMS microphones inherently have a very usable ultrasonic response from 20kHz to 80kHz or more. The output of the u/s signal must be processed by an amp, CODEC, or ADC that can extract the needed frequencies, usually by using a higher sample rate and/or lower decimation rate. MEMS microphones are reflow capable SMT devices with stable performance under extreme conditions. They are resistant to power supply noise, humidity, and mechanical shock and vibration. Compared to ECMs, MEMS microphones have wide operating temperature and supply voltage ranges where sensitivity does not drift.
