Digital audio PDM-to-PCM converter with 117 dB Dynamic Range and Dual-phase alignment

The YANZI-D-octDSA-YA3-VD.01 is a PDM-to-PCM converter to interface with digital microphones.

Overview

The YANZI-D-octDSA-YA3-VD.01 is a PDM-to-PCM converter to interface with digital microphones. This product optionally includes a unique VAD feature and an Automatic Gain Control (AGC) for ensuring the best quality of the recording sound whatever the end-user environment.
It also features DMIC compensation and dual phase synchronisation between the input channels to ensure high performance AR/VR, beamforming and smartspeaker applications.

Key features

  • PDM to PCM converter with 8 input channels
  • WhisperTrigger - low power Voice Activity Detector
  • I2C and APB control interface
  • Direct connection to digital microphones
  • Automatic Gain Control (AGC)
  • High dynamic range for high quality recording in far-field applications
  • Dual phase alignment feature to prevent phase mismatch in beamforming applications
  • DMIC phase adjustment to compensate for DMIC samples misalignment
