PDM Receiver/PDM-to-PCM Converter
- This PDM2PCM is a configurable audio interface core that converts a mono or stereo Pulse Density Modulation (PDM) stream into standard Pulse Code Modulation (PCM) format.
- PCM output widths are programmable from 2 to 32 bits, and all standard audio sampling rates are achievable via an adjustable Oversampling Ratio (OSR) from 32x to 256x.
