TUSB8041: Timing diagram confirmation

Part Number: TUSB8041

Hi 

My customer is conducting power up timing sequence on TUSB8041. The native system has an reset initial pulse at GRSTz pin during power on. It is tested the USB hub able to function with GRSTz asserted high after 30ms. Could you help to check the waveform below and advise if you see any concern need to be addressed ?

    Hi Kelvin,

    The full GRSTz pulse after the system powers on meets the datasheet requirements.  It is recommended that GRSTz stay low initially, but the quick pulse high followed by a complete reset should not cause any issues.
