Important Notice

Safety and Hazards

Due to the nature of wireless communications, transmission and reception of data
can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be
totally lost. Although significant delays or losses of data are rare when wireless
devices such as the Sierra Wireless modem are used in a normal manner with a
well-constructed network, the Sierra Wireless modem should not be used in
situations where failure to transmit or receive data could result in damage of any
kind to the user or any other party, including but not limited to personal injury,
death, or loss of property. Sierra Wireless accepts no responsibility for damages
of any kind resulting from delays or errors in data transmitted or received using
the Sierra Wireless modem, or for failure of the Sierra Wireless modem to
transmit or receive such data.

Do not operate the Sierra Wireless modem in areas where blasting is in progress,
where explosive atmospheres may be present, near medical equipment, near life
support equipment, or any equipment which may be susceptible to any form of
radio interference. In such areas, the Sierra Wireless modem MUST BE
POWERED OFF. The Sierra Wireless modem can transmit signals that could
interfere with this equipment.

Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE
POWERED OFF. When operating, the Sierra Wireless modem can transmit
signals that could interfere with various onboard systems.

Limitation of Liability

Note: Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. Sierra Wireless modems may be used at this time.

The driver or operator of any vehicle should not operate the Sierra Wireless
modem while in control of a vehicle. Doing so will detract from the driver or
operator's control and operation of that vehicle. In some states and provinces,
operating such communications devices while in control of a vehicle is an offence.

The information in this manual is subject to change without notice and does not
represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND
ITS AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL
DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL,
PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO,
LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE
ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE
FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.

Notwithstanding the foregoing, in no event shall Sierra Wireless and/ or its
affiliates aggregate liability arising under or in connection with the Sierra Wireless
product, regardless of the number of events, occurrences, or claims giving rise to
liability, be in excess of the price paid by the purchaser for the Sierra Wireless
product.

1: Introduction

Sierra Wireless’ AirPrime Intelligent Embedded Modules form the
radio component for the products in which they are embedded.

The AirPrime MC7750 is available for use on LTE, CDMA, and GSM
networks.

Note: An understanding of network technology, and experience in integrating
hardware components into electronic equipment is assumed.

Purpose of this guide

This guide addresses issues that affect the integration of AirPrime
embedded modules into host products, and includes design
recommendations for the host products.

The Universal Development Kit

Sierra Wireless manufactures a Universal Development Kit (UDK)
that facilitates all phases of the integration process.

This kit is a hardware development platform that is designed to
support AirPrime Mini Card embedded modules. It contains the
hardware components that are typically necessary for evaluating and
developing with the module, including:

• Development board

• Cables

• Antennas

• Other accessories

For instructions on setting up the UDK, see PCI Express Mini Card
Dev Kit Quick Start Guide (Document 2130705).

Required connectors

Note: Contact vendors
before choosing your
connectors—the numbers
included here are for
reference only. Choose
connectors that are appro­priate to your design.

Rev 3.0.2 Mar.11 Proprietary and Confidential 7

When integrating AirPrime embedded modules into your host device,
you need the following connector types:

• RF cables that mate with Hirose U.FL connectors (model
U.FL #CL331-0471-0-10). Modules include one to three
connector jacks depending on individual module support for
diversity or GPS functionality.

• Industry-standard mating connector for 52-pin EDGE—some
manufacturers include Tyco, Foxconn, and Molex. For example,
the connector used on the Mini Card Dev Kit board is a Molex
67910-0001.

AirPrime MC7750 Hardware Integration Guide

• Industry-standard USIM connector — the actual connector you use depends
on how your device exposes the USIM socket. For example, the USIM
connector used on the Mini Card Dev Kit board is an ITT CCM03-3518.

2: Power Interface

Overview of operation

AirPrime embedded modules are designed to use a 3.3V (nominal)
power supply provided by the host. It is the host’s responsibility to
provide safe and continuous power to the module at all times; the
module does NOT have an independent power supply, or protection
circuits to guard against electrical issues.

The module’s power state is controlled by the host’s assertion/

deassertion of W_Disable#. The module also monitors its supply

voltage and requests shutdown if the supply is insufficient.

Power signals

The module must be connected to a 3.3V power supply, as described
in PCI Express Mini Card Electromechanical Specification Revision

1.1.

For detailed pinout and voltage/current requirements, see the
Product Specification Document for your AirPrime embedded
module.

Power supply

Table 2-1: Power supply requirements

Requirement type Value

Power supply 3.3 V (nominal)
Voltage range 3.0–3.6 V
Maximum peak current (worst-case) 2.75 A

Electrostatic discharge (ESD)

You are responsible for ensuring that the host has adequate ESD
protection on digital circuits and antenna ports as described by the
following specifications:

• (Operational) RF port (antenna launch and RF connector): IEC­61000-4-2—Level (Electrostatic Discharge Immunity Test)

• (Non-operational) Host connector interface: JESD22-A114-B +/-

1kV Human Body Model and JESD22-C101 +/- 125 V Charged

Device Model

This guide provides specific recommendations where needed,
however, the level of protection required depends on your application.
