UTMI 12MHz Clock Input:
This pin provides the 12MHz clock signal input form
external crystal or oscillator.
UTMI 12Mhz Clock Output:
This pin should be connected with the other end of
the 12Mhz crystal or left unconnected if an external
oscillator is used
USB 48 MHz clock input:
This signal provides the fundamental clock for the USB
Controller.
USB Port 0-5 Overcurrent Detection:
OC[0:5]# are used to detect the overcurrent condition of
USB Ports 0-5.
USB Port [3:0] Differential:
These differential pairs are used to transmit
Data/Address /Command signals for ports 3 and 0. (USB
controller 0)
USB Port [4:1] Differential:
These differential pairs are used to transmit
Data/Address/Command signals for ports 4 and 1. (USB
controller 1)
USB Port [5,2] Differential:
These differential pairs are used to transmit
Data/Address/Command signals for ports 5 and 2. (USB
controller 2)
USB reference resistor input:
A resistor should be connected to USBVSS from this pin
for IO impedance calibration.
