I would like to verify with you, does ADV7612 support 8-channels audio with 192 kHz sample rate?
In UG-216 document I found that ADV7612 supports:
- The ADV7612 supports the extraction of stereo audio data (noncompressed or compressed) at audio sampling frequency up to 192 kHz.
- The ADV7612 supports the extraction of multichannel audio data.
As ADV7612 has multiple I2S channels, I would assume that it should be able to source 8 channels at 192 kHz, but I cannot find that information in datasheet nor hardware manual.
