120dB PDM-to-PCM Digital Microphone Interface
The AR36T05 is a soft macro low-power high-performance digital microphone interface modulator IP.
Overview
The AR36T05 is a soft macro low-power high-performance digital microphone interface modulator IP. The IP converts stereo/mono 1-bit pulse-density modulated (PDM) bit stream data from external digital microphones into 16-24bit pulse-code modulated (PCM) data for base-band processing. It is expandable to multi-channel system for various voice and audio applications.
The IP is portable to any logic process node for silicon realization. It is now silicon-proven in TSMC 16nm and 28nm logic processes.
