Part Number: TUSB8041

Hi,

When should I enable it when using an external clock source instead of the internal oscillator?

Thanks.

external clock should be stable before GRSTz goes high. it's better available hen power is on.

I think it should be given after the power supply rails are stable, right?

right, but make sure GRSTz has enough time for reset.
