TUSB8020B: Rise time specification for VDD33

Part Number: TUSB8020B

Hi,

Based on the datasheet, there is a minimum ramp up time requirement for both the 3.3V and 1.2V supply.  What is the purpose of this minimum requirement?

Currently on our setup, the 3.3v supply rise time is around 30us. We've tried adding 10uF to the supply line but the rise time only at ~50us. Would like to know if this will impact the functionality/performance of the IC?

Thanks.
