7 Interfacing to the PCIe M.2 Module

 Power and Ground

All circuits on the PCIe M.2 Module are powered from inputs at pin 2, 4, 70, 72 and 74. The PCIe M.2

Module operates with any supply voltage between 3.135 and 4.4V, The Power pins follow PCIe M.2

design rule.

 Communication

The PCIe M.2 Module has one USB 2.0 ports. The USB are compatible with a standard USB 2.0. The user’s

host processor issues IRI commands to the HOST USB, which can be configured for any standard USB 2.0.

 RF

The PCIe M.2 Module is configured for monostatic operation, which requires only a single RF port for full

duplex communication. The output must be routed to the antenna via 50 ohm. To maximize the radiated

power (and corresponding communication range), the length of the transmission line between PCIe M.2

Module and antenna should be made as short as possible.

 W_Disable1#

W_Disable1# is wireless disable signals that are provided for wireless communications add-in cards. This

signal allow users to disable, via a system-provided switch, the add-in card’s radio operation in order to

meet public safety regulations or when otherwise desired. Implementation of wireless disable signals is

applicable to systems and all add-in cards that implement radio frequency capabilities.

 Full_Card_Power_Off#

FULL_CARD_POWER_OFF# signal is an Active Low input that is used to turn off the entire module. When the

input signal is asserted high ( 1.19 V) the Module  will be enabled. When the input signal is driven low signal

(≤0.2 V) or Tri-stated, it will force the module to shut down.

 Reset#

Asynchronous RESET# pin, active low. Whenever this pin is active, the modem will immediately be placed in a

Power On reset condition. Care should be taken not to activate this pin unless there is a critical failure and all

other methods of regaining control and/or communication with the PCIe M.2 Module have failed.

When the input signal is asserted high ( 1.19 V) the Module will be  operation mode. When the input signal is

driven low signal (≤0.2 V) the Module will be reset PCIe M.2 Module.

 LED_1#

Open drain, active low signal. This signals is used to allow the

add-in card to provide status indicators via LED devices that

will be provided by the system.
