Part Number: TUSB8041

Hi Experts,

Our customer wants to know how about the response time for TUSB8041 after GRSTz pin is de-assertion to full function? Can you help to check for this time?

Thanks.

    Hi Jacky,

    The hub will be ready to function after reset completes and it is configured.  If the hub is being configured by SMBUS or I2C, this must finish before the hub is ready to function.  For pin configuration, the pins are sampled after reset and the hub will be ready to function within microseconds, but 1 ms is a good buffer range.

    Regards,
