Hi Wells,

May I learn from you if LM49352 support PDM?

I only saw it support PCM.

Many thanks,

Patrick

Patrick,

you are correct, there is no PDM support on the LM49352, only PCM.

we definitely have devices that can accept PDM inputs, AIC3106, AIC3212, AIC3204 etc... but I'm not aware of any of our Codecs that would take I2S and convert to PDM. This is not a feature supported by our current codec portfolio.

best regards,
