...made from PCM and what?

A DSD modulator? And how is the PCM output made if the ADC is actually an oversampled 5-bit sigma-delta ADC?

 

[IVX]

no idea.

 

[torgeirs]

Don’t know if it gives anything away, but RAW data taken from the input of new ADC is 8 parallell bits every masterclock
So a substential datarate, 2 bits pr input phase each masterclock period

 

[torgeirs]

So maybe time multiplex more channels like the mcu sar ADCs
Or downsampling and averaging for mid + lf + unchanged hf. Fir first and joining after.
Things that is done im mcus today for normal signal conditioning
