3.3.2.6. USB
3.3.2.6.1. Description
The NAD6200 module has one USB 2.0 high speed compliant interface with built-in PHY.
The USB Interface consists of 4 signals:
- USB_DP: USB Data Plus signal
- USB_DM: USB Data Minus signal
- USB_VBUS: USB Voltage Supply
- USB_GND: USB Ground
The NAD6200 module is configured as USB – Device on the NAD6200 PCB.
This Interface supports the following data rates:
- At low – speed: 1.5 Mbit/s
- At full – speed: 12 Mbit/s
- At high – speed: 480 Mbit/s

If there is a requirement that the system must power the USB_VBUS while the module is not switched
on, it is strictly recommended to limit the USB_VBUS current to the module by a serial resistor of 22 KΩ.
