The SAM3U4E UDPHS port is compliant with the Universal Serial Bus (USB) rev 2.0 High Speed device
specification. J9 is a B-type receptacle for USB device.
Both R2 and R3 39-Ohm resistors build up a 90-Ohm differential impedance together with the 5-Ohm
output impedance of the Hi-speed channel drivers.
R68 and R69 build up a divider bridge from VBUS +5V to implement plug-in detection (5V level gets low-
ered to a PIO compatible 3.3V level) through PA0. Note that PA0 is also shared with ZigBee signal IRQ0.
