PDM to PCM Conversion, SMIC 65nmLL

Overview

The AR36S01 is a soft macro low-power digital microphone interface modulator IP. The IP converts stereo/mono 1-bit pulse-density modulated (PDM) bit stream data from external digital microphones into 16-22bit pulse-code modulated (PCM) data for base-band processing.

The IP is portable to any logic process node for silicon realization. It is now silicon-proven in SMIC65nm logic process.
