General • Would Pico work with AK4619VN? (TDM 4ch slave)

Hi,

The chip is a codec with 4-ch TDM slave support https://www.akm.com/eu/en/products/audi ... /ak4619vn/

This https://arduino-pico.readthedocs.io/en/ ... t-channels says:

bool setTDMChannels(int channels)
Sets the number of TDM channels between frame syncs. Generally should be set to 8.

Why "generally to 8"?

Would an external oscillator be necessary or Pi generating MCLK would be possible/good enough?

I would need 4 channel duplex, 24 or if possible 48kHz. The processing on Pi would be quite simple.
