Hello.

My customer will use the CY7C65621-56LTXI.

They use 3 Downstream port.

They don't use OVR#[4].

Their schematic doesn't have the pull-up resister for the OVR#[4].

What problems might occur?

Please check it.

Thanks and Best regards.

Glenn.

Hello Glenn,

The OVR#[4] can be left unconnected as it has internal pull up present, please refer to the default pin state from the datasheet. The customer can also configure the hub using the EEPROM to disable DS4.

Best Regards,

Sananya
