DS90UB964-Q1: Why need to set the minimum value for the rise time?

Dear team,

Could you please tell me why do we need to set the minimum value for the rise time? Sometimes the customer can't meet the requirement, so they want to know why we set the minimum value.

Thanks & Best Regards,

Sherry

    Hello Sherry,

    The minimum rise time is to ensure that all internal circuits have properly powered up during the boot sequence. If the ramp time is exceedingly fast, some analog circuits may not power up into the correct state so it is important to always follow the guidelines in this table. 

    Best Regards,
    Casey
