Description
positive differential USB3.0 Tx signal for COM port
negative differential USB3.0 Tx signal for COM port
3.3V +/-10% power supply
positive differential USB3.0 Rx signal for COM port
negative differential USB3.0 Rx signal for COM port
positive differential USB2.0 signal for COM port
negative differential USB2.0 signal for COM port
USB_ID for COM port
3.3V +/-10% power supply
switch logic control for SuperSpeed Path
If HIGH, then path B is selected for SuperSpeed channels only
If LOW, then path A is selected for SuperSpeed channels only
Output enable. if OE is low, IC is enabled. If OE is high, then IC is power
down and all I/Os are hi-z
3.3V +/-10% power supply
