LMK03318: How long after PDN L -> H to wait before I2C transactions are allowed and valid?

Part Number:LMK03318

Hello,

What is the worst case delay I need to build into my system between the LMK03318 being brought out of reset via PDN and the first communication on the I2C bus?

I'm using LMK03318 in soft pin mode, and I can usually communicate with the device via I2C 100 ms after the PDN pin is brought high. But sometimes, it seems like it needs more time.

Thanks,

Jonathan
