I'm not familiar with I2S but if you need to communicate at 100kHz through a bidirectional open drain protocol, then I believe this may be a suitable…
"VCC is 3V3. So B side to A Side right ?"
B to A is okay. But for cable transmission I would have both A sides face the cable.
"It is said that the P82B715 is a device for buffering highly capacitive I 2C bus systems, up to 3000nF !"
It can technically…
