representatives from hardware, software and RF engineering disciplines.
1.3 DISCLAIMER
This guide provides advice and guidelines to OEM teams. Responsibility regarding how the information is used lies entirely
with the OEM. Statements indicating support provided by, or offered by, Motorola are subject to change at any time.
Motorola reserves the right to make any changes to this manual.
1.4 REGULATORY REQUIREMENTS
The Federal Communications Commission (FCC) requires application for certification of digital devices in accordance with
CFR Title 47, Part 2 and Part 15. This includes Electromagnetic Energy Exposure (EME) testing. As the g20 modem is not a
standalone transceiver but is an integrated module, the g20 cannot be tested by itself for EME certification. It is, however, the
integrator’s responsibility to have the completed device tested for EME certification.
1.5 REGULATORY STATEMENT
The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular
terminal or mobile incorporating the g20 module. Manufacturers of the cellular terminal are advised to convey the following
safety information to users and operating personnel, and to incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product.
Motorola assumes no liability for customer failure to comply with these precautions.
1. The g20 must be operated at the voltages described in the technical documentation.
2. The g20 must not be mechanically nor electrically changed. Use of connectors should follow the guidance of the technical
documentation.
3. The g20 is designed the meet the EMC requirements of ETS 300 342.
98-08901C64-O 1
Preface
DRAFT 1 (31.3.03)
4. When integrating the g20 into a system, Motorola recommends testing the system to ETS300342-1.
5. The g20 meets the safety requirements of EN60950.
6. Systems using the g20 are subject to mandatory EMC testing under directive 89/336/EEC (see item 3 above). Other
directives, such as the LVD directive 73/23/EE, may also apply to a system using the g20 module.
1.6 SAFETY
1.6.1 User Operation
Do not operate your telephone when a person is within eight inches (20 centimeters) of the antenna. A person or object within
eight inches (20 centimeters) of the antenna could impair call quality and may cause the phone to operate at a higher power level
than necessary, as well as expose that person to RF energy in excess of that established by the FCC RF Exposure Guidelines.
IMPORTANT: The telephone must be installed in a manner that provides a minimum separation distance of 20 cm or more
between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting devices.
IMPORTANT: To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile
transmitters, the requirements described in the section that follows must be met.
1.6.2 Antenna Installation
• A minimum separation distance of 20 cm must be maintained between the antenna and all persons.
• The effective radiated power of the transmitter must be less than 1.5 Watts ERP (2.45 Watts or 33.9 dBm EIRP). This requires
that the combination of antenna gain and feed line loss does not exceed 11 dBi.

3.2 COMMUNICATIONS INTERFACES
The g20 Developer Board includes three different serial interfaces:
•RS232
•USB
• SPI
The RS232 and USB ports are multiplexed within the g20, and therefore cannot be operated simultaneously. Their default
connection is RS232. The SPI interface is used for debugging.
Each of these serial interfaces is described in the sections that follow.
3.2.1 RS232
The RS232 serial port is the primary interface to the g20 UUT via the J350 connector. This port is denoted by the RS232-1
marking beside the 9-pin, D-type connector.
The UUT RS232 signals are active-low CMOS-level signals (0-2.7 V), which are converted by the Developer Board to standard
RS232 levels for PC communications.

3.4 POWER CONNECTIONS
Developer Board power can be supplied from a DC power source, an AC power adapter or a battery. The same power source is
used for the UUT and the board peripherals.
The Developer Board includes three jumpers for controlling the power supply:
• P202: AC adapter or battery power source selection
• P201: Connects/disconnects the Developer Board peripherals from the power supply
• P200: Connects/disconnects the g20 from the power supply
Each power supply option is described in the sections that follow.
3.4.1 DC Power Source Operation
When using a DC power supply, the power source is applied to connectors J201 (VCC) and J200 (Ground). The DC voltage
applied through this connection should not exceed the recommended operational limits of 3V-4.2V. In all cases, the DC source
input is protected from over voltage and reverse polarity, and includes a 2.5A protective fuse.
The supplied DC input connectors must be attached to the Developer Board in order to use the DC power source. The two
connectors should be screwed into their appropriate positions (J201, labeled VCC, and J200, labeled GND). Use the red connector for VCC and the black one for GND. Connect the DC power source to these connectors using banana plugs, alligator clamps
or wire.
It is recommended to remove jumper P202 when using the DC power source. In any case, the DC power source
should not be used when other sources are connected.

3.8.4 Headset
The headset interface is designed as a portable phone audio interface, and is similar to the headset interface. The headset connector (J440) includes a speaker, microphone and a detection signal. The speaker and microphone signals are directly connected to
the g20 audio signals.
The purpose of the detection circuit is to switch the g20 headset audio paths on and off, whenever a headset connection is
detected. Headset detection is made whenever a headset plug is inserted into the jack. This action disables the g20 microphone
and speaker, and routes the audio signals to the headset.

3.9.2 Entertainment Mute
The Developer Board includes an entertainment-mute logic circuit that is responsible for muting a car radio whenever the phone
is in use (for example, incoming calls, dialing, and so on).
The entertainment-mute logic circuit includes an ENABLE input that is both a g20 signal and an open-collector MUTE output.
This circuit is connected to jumper P130 for host systems.
The entertainment-mute operation is not currently supported by the g20.
Note
3.9.3 LEDs Logic and Control
The Developer Board includes LED indicators for critical signals. A 3.0V regulator powers the LEDs, and an on/off switch
controls their operation. The switch is located in the S100 switch array, and is labeled LED. Turning the switch on and off
enables or disables all LED activity, respectively.
The Developer Board power LED and the g20 on/off LED are always active and cannot be disabled.
3.9.4 ADC Test Logic
The g20 has two ADC pins. The g20 charger and temperature monitor currently occupy these pins. The Developer Board
includes optional resistors for ADC testing. These resistors, two for each ADC signal, can be used to set a specific voltage across
the ADC signal.
24 98-08901C64-O
Developer Board and Interfaces Description
DRAFT 1 (31.3.03)
The G20 has a 47K-ohm internal pull-up resistor at each ADC input, as shown in Figure 5.
Figure 5. ADC Test Logic
3.9.5 Ignition
The Developer Board contains an on/off switch that is connected to the g20 UUT ignition circuit. The switch is located in the
S100 switch array, and is labeled IGN. Turning the switch on applies the UUT supply on the Ignition input pin.
3.9.6 Wakeup
The Developer Board includes a wakeup switch that toggles the g20 WAKEUP_IN_N signal. The switch is located in the S100
switch array, and is labeled WAKEUP.
3.9.7 AC Adapter Detection Circuit
The g20 charger module includes a detection logic circuit for detecting charger presence and type. The detection circuit is internal to the g20 module. However, the Developer Board does contain the necessary routing from the g20 UUT to the AC adapter
connector.
Two g20 signals are used for this detection:
• AD1: ADC signal for charger type detection
• CHRG_SW: Charger rate control
These detection signals are present to provide compatibility with the phone. They may be removed in future versions.
3.10 ANTENNA CONFIGURATION
An antenna (internal or external) must be connected to the Developer Board for adequate GSM reception. You can connect the
g20 to either the on-board internal antenna or to an external antenna. Two RF connectors on the Developer Board, labeled INT
ANT and EXT ANT, are used for this purpose. The EXT ANT connector has an internal extension cable with MMCX termination, which must be connected to the g20 RF connector. The INT ANT connector is an on-board connection to the Developer
Board internal antenna.
When using the internal antenna option, the additional RF cable supplied in the Developer’s Kit must be connected between the
EXT ANT and INT ANT connectors. When using the external antenna option, an external antenna or antenna application must
be connected to the EXT OUT connector. (The connection cable is not included.)
