Does AD7403(-EP) supports a temporary loss of MCLKIN without power loss ?
When the clock restarts without power cycle, does the IC behave nominally (as if it has just been powered on) ?
I'm thinking that should be fine. What would be not recommended is to have MCLKIN without the supply first. So if the MCLK was lost for some time then it is expected that there will be no conversion during the absence of MCLK but once it was powered up and settle then I am expecting that the part should work normally.
May I know the reason for the ask? Are you having some issues? Can you share us more details about it?
