Default Raspberry Pi I2S question


my osciloscope died some days ago, so i can't measure the rpi i2s lines. I need to know the voltages. Digital zero is around 0v (or 0.1V), but what is the voltage of digital 1 on the i2s line ? Is it 5V, 3.3V or even 2V ? I need to know this for my reclocker and isolator.

Many thanks

Nobody knows ? Is it the standard 2V mentioned in the i2s specs ? Is the voltage different in the clocks and the data lines ?
