Hello, community


The i.MX8QXP has TWO USB OTG ports.

According to the IMX8QXP DataSheet (Rev.0),

VBUS (OTG2) -0.33.63V : (VBUS level is limited to 3.3V)

VBUS (OTG1) -0.35.5V : (VBUS level is limited to 5V)

But  p100, Table 101 (USB 2.0 PHY OTG comparator specifications) list only one type of  vbusvalid.

That is , min 4.4V to max 4.75V. It looks like vbusvalid in OTG 1.

Please let me know What about vbusvalid in OTG 2?


Best Regards,
