- USB_D_P:

USB Data Plus signal

- USB_D_M:

USB Data Minus signal

- USB_ID:

Master/Slave Configuration

- USB_VBUS:

USB Voltage Supply

- 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
