What amplitude SYNC_CLK signal is going to be when DVDD_I/O is powered from 3.3V ?
IYes you can use it asynchronously without observing the SYNC_CLK and I would like to suggest more than 2 SYNC_CLK periods just to be sure.
The expected swing would be a few mV above 0 V then up to 3.3 V.
Thank you. Do I need to sync I/O UPDATE with SYNC_CLK edge observing specified setup time or I can do IO UPDATE asynchronously and just hold it for at least two SYNC_CLK periods?
Here is a screenshot of SYNC_CLK with DVDD_IO at 3.3V.
Thank you Louigie and Mark!
