VREG_USB3_3V075 USB Voltage Output
A dynamic reconfiguration between USB-Host or USB-Device is not foreseen, the NAD can be configured
to USB-Host or USB-Device by the insertion of a resistor on the
USB_ID line
.
3.3.2 SIM Interface
The NADs SIM interface is compatible to 1.8V and 3V SIM Cards, the necessary voltage and level shifting
is handle by LTE-NAD automatically. The IF consists of the following signals:
VREG_USIM
USIM_CLK
USIM_DATA
USIM_RESET
The data speed on the SIM IF is up to 4 Mbps, so HW designers should take care of the length and
routing of the SIM IF to prevent potential EMC problems.
3.3.3 Power on
The signal PON_N is used switch on the NAD-Module. PON_N is pulled against VMAIN on the
LTE-NAD internally.
Due to this fact it is recommended to pull this input against GND using an open collector or
open drain output only.
3.3.4 Reset
EXT_RESIN_N
is used to reset the LTE-NAD-Module, see table of LTE-NAD signal pins.
There are further reset signals available, please check .
RES_IN is pulled against VMAIN power on the LTE-NAD internally. Therefore, it is
recommended to pull this input against GND using an open collector or open drain output only.
3.3.5 GPIOs

The LTE-NAD is configured in the slave mode. For other configuration of the USB – Interface please contact
