1.3 Regulatory and Type Approval Information

1.3.3 SELV Requirements

The power supply connected to the XT65/XT75 module shall be in compliance with the SELV requirements defined in EN 60950-1. See also Section 6.1 for further detail.

1.3.4 Safety Precautions

The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating XT65/XT75. 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. Siemens AG assumes no liability for customer’s failure to comply with these precautions.

When in a hospital or other health care facility, observe the restrictions on the use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy.

The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on.

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both.

Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard.

Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger.

Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile, park the vehicle.

Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard.

XT65/XT75 Ha rdware Interface Overview

1.3 Regulatory and Type Approval Information

IMPORTANT!

Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls.

Remember, in order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.

Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call.

Some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.

Bear in mind that exposure to excessive levels of noise can cause physical damage to users! With regard to acoustic shock, the cellular application must be designed to avoid unintentional increase of amplification, e.g. for a highly sensitive earpiece. A protection circuit should be implemented in the cellular application.

XT65/XT75 Ha rdware Interface Overview

3.1 Operating Modes

The table below briefly summarizes the various operating modes available for the module.

Table 5: Overview of operating modes

Normal operation GSM / GPRS SLEEP Various power save modes set with AT+CFUN command.

Software is active to minimum extent. If the module was registered to the GSM network in IDLE mode, it is registered and paging with the BTS in SLEEP mode, too. Power saving can be chosen at different levels: The NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes AT+CFUN=7 and 9 alternatingly activate and deactivate the AT interfaces to allow permanent access to all AT commands.

GSM IDLE Software is active. Once registered to the GSM network, paging

with BTS is carried out. The module is ready to send and receive.

GSM TALK Connection between two subscribers is in progress. Power con-

sumption depends on network coverage individual settings, such as DTX off/on, FR/EFR/HR, hopping sequences, antenna.

GPRS IDLE EGPRS IDLE

GPRS DATA EGPRS DATA

POWER DOWN Normal shutdown after sending the AT^SMSO command.

Only a voltage regulator is active for powering the RTC. Software is not active. Interfaces are not accessible. Operating voltage (connected to BATT+) remains applied.

Airplane mode Airplane mode shuts down the radio part of the module, causes the module to log off from

the GSM/GPRS network and disables all AT commands whose execution requires a radio connection.

Airplane mode can be controlled by using the AT commands AT^SCFG and AT+CALA:

• With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured to enter the Airplane mode each time when switched on or reset.

• The parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth between Normal mode and Airplane mode any time during operation.

• Setting an alarm time with AT+CALA followed by AT^SMSO wakes the module up into Airplane mode at the scheduled time.

Module is ready for GPRS/EGPRS data transfer, but no data is currently sent or received. Power consumption depends on network settings and GPRS/EGPRS configuration (e.g. multislot settings).

GPRS/EGPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink / downlink data rates, GPRS configuration (e.g. used multislot settings) and reduction of maximum output power.

Charge-only mode Limited operation for battery powered applications. Enables charging while module is

detached from GSM network. Limited number of AT commands is accessible. Chargeonly mode applies when the charger is connected if the module was powered down with AT^SMSO.

4 GSM Antenna Interface

The GSM interface has an impedance of 50Ω. XT65/XT75 is capable of sustaining a total mismatch at the antenna connector without any damage, even when transmitting at maximum RF power. DC electric strength is given (see Table 11).

The external antenna must be matched properly to achieve best performance regarding radiated power, DCpower consumption, modulation accuracy and harmonic suppression. Antenna matching networks are not included on the XT65/XT75 PCB and should be placed in the host application.

Regarding the return loss XT65/XT75 provides the following values in the active band:

4.1 Antenna Installation

To suit the physical design of individual applications XT65/XT75 offers two alternative approaches to connecting the antenna:

• Recommended approach: U.FL-R-SMT antenna connector from Hirose assembled on the component side of the PCB.

Figure 1: GSM antenna connector placement

See Section 4.3 for connector details.

• Antenna pad and grounding plane placed on the bottom side. See Section 4.2.

The U.FL-R-SMT connector has been chosen as antenna reference point (ARP) for the Siemens reference equipment submitted to type approve XT65/XT75. All RF data specified throughout this manual are related to the ARP. For compliance with the test results of the Siemens type approval you are advised to give priority to the connector, rather than using the antenna pad.

IMPORTANT: Both solutions can only be applied alternatively. This means, whenever an antenna is plugged to the Hirose connector, the pad must not be used. Vice versa, if the antenna is connected to the pad, then the Hirose connector must be left empty.

4.2 Antenna Pad

The antenna can be soldered to the pad, or attached via contact springs. For proper grounding connect the antenna to the ground plane on the bottom of XT65/XT75 which must be connected to the ground plane of the application.

If you decide to use the antenna pad take into account that the pad has not been intended as antenna reference point (ARP) for the Siemens XT65/XT75 type approval. The antenna pad is provided only as an alternative option which can be used, for example, if the recommended Hirose connection does not fit into your antenna design.

Please ensure that the antenna pad does not come into contact with the holding device or any other components of the host application. It needs to be surrounded by a restricted area filled with air, which must also be reserved

0.8mm in height.

4.2 Antenna Pad

Also, consider that according to the GSM recommendations TS 45.005 and TS 51.010-01 a 50Ω connector is mandatory for type approval measurements. This requires GSM devices with an integral antenna to be temporarily equipped with a suitable connector or a low loss RF cable with adapter.

Figure 3: GSM antenna pad placement

Notes on soldering:

• To prevent damage to the module and to obtain long-term solder joint properties you are advised to maintain the standards of good engineering practice for soldering.

• Be sure to solder the antenna core to the pad and the shielding of the coax cable to the ground plane of the module next to the antenna pad. The direction of the cable is not relevant from the electrical point of view.

XT65/XT75 PCB: FR4

Antenna pad: Gold plated pad

4.2.1 Suitable Cable Types

For direct solder attachment, we suggest to use the following cable types:

• RG316/U 50Ohm coaxial cable

• 1671A 50Ohm coaxial cable

Suitable cables are offered, for example, by IMS Connector Systems. For further details and other cable types please contact http://www.imscs.com

Please note that the GSM antenna must be isolated for ESD and SAR protection (to withstand a voltage resistance up to 8kV air discharge).

5 GPS Antenna Interface

In order to receive satellite signals an additional GPS antenna must be connected to the GPS part of the XT65/ XT75 module.

5.1 Antenna Installation

To suit the physical design of individual applications XT65/XT75 offers two alternative approaches to connecting the antenna:

• Recommended approach: U.FL-R-SMT antenna connector from Hirose assembled on the component side of the PCB. The GPS antenna connector is the same as for the GSM antenna connector. For details see Section

5.3.

Figure 8: GPS antenna connector placement

• Antenna pad and grounding plane placed on the bottom side of the PCB. For some notes on soldering the antenna to the pad see Section 5.2.

Figure 9: GPS antenna pad placement

Note that it is not possible to employ both alternatives at the same time.

XT65_XT75_HO_v00.130 Page 27 of 67 2006-10-12 Confidential / Preliminary

XT65/XT75 Ha rdware Interface Overview

5.2 GPS Antenna

It is possible to connect active or passive GPS antennas. In either case they must have 50 Ohm impedance. The application should be designed in a way to achieve a minimum of 6dB decoupling between the GSM/DCS/PCS antenna path and the GPS antenna path. Please note that the GPS antenna must be isolated for ESD protection (to withstand a voltage resistance up to 8kV air discharge).

Active versus Passive Antennas

Passive antennas contain only the radiating element, e.g. the ceramic patch or the quadrifilar dipole structure. Sometimes they also contain a passive matching network to match the electrical connection to 50 Ohms impedance. Note: Passive antenna need not have a DC connection to ground.

Active antennas have an integrated low-noise amplifier (in some cases an additional GPS band pass filter). This is beneficial in two respects: First, the losses of the cable do no longer influence the overall noise figure of the GPS receiver system. Secondly, even the receiver noise figure can be higher without sacrificing performance. Active antennas need a power supply that will contribute to GPS system power consumption, typically in the region of 5 to 20 mA. The supply voltage is fed to the antenna through the coaxial RF cable.

Inside the antenna, the DC component on the inner conductor will be separated from the RF signal and routed to the supply pin of the LNA.

The use of an active antenna is always advisable, if the RF-cable length between receiver and antenna exceeds about 10 cm.

Table 10: GPS antenna: Active versus Passive

Active Antenna Passive Antenna

Active antenna connected to the GPS module. Passive patch antennas or quadrifilar dipole antennas con-

nected with a microcoax to the GPS module

• A wide range of active patch or quadrifilar dipole antennas is available in the market. They differ in size, sensitivity, selectivity and power consumption

• Less sensitive to jamming than a passive antenna, as the placement of the active antenna is usually some distance away of other noise or signal radiating devices.

• Needs more power than a passive antenna

• Easier and less sensitive to jamming.

• More freedom to place the antenna

Some cars for instance have a metallic coating on the windshield. GPS reception may not be possible in such a car. There is usually a small section, typically behind the rear view mirror without the coating for mobile phone and GPS antennas. The antenna has to be placed with optimal sky visibility. An external antenna (e.g. with a magnetic base) is easier to use and usually allows a better positioning.

• Passive patch antennas or helical antennas are available in different form factors and sensitivity

• Antenna must be connected with a low insertion loss line to the GPS module to ensure a good GPS sensitivity.

• The PCB design with a passive antenna must consider the sensitivity of the GPS antenna to other radiating circuits or general signal jamming.

• Due to the proximity of the GPS antenna to other electronic circuits, in-band jamming may become a critical issue.

• Only suitable for RF experts!

• Needs more experience in RF design.

• Requires more effort to optimise the circuit design to minimize jamming into the antenna and the antenna signal routing.

Note: If you are not an expert in RF designs, you should implement an active antenna setup and place the

antenna away from any emitting circuits.

PWR_IND (Power Indicator) notifies the module’s on/off state.

PWR_IND is an open collector that needs to be connected to an external pull-up resistor. Low state of the open collector indicates that the module is on. Vice versa, high level notifies the Power-down mode.

Therefore, the pin may be used to enable external voltage regulators which supply an external logic for communication with the module, e.g. level converters.

This signal switches the mobile on.

This line must be driven low by an open drain or open collector driver.

Reset or shut down in case of emergency: Pull down and release EMERG_RST. Then, activating IGT for 400ms will reset XT65/ XT75. If IGT is not activated for 400ms, XT65/XT75 switches off.

Data stored in the volatile memory will be lost. For orderly software controlled reset rather use the AT+CFUN command (e.g. AT+CFUN=x,1).

This line must be driven by open drain or open collector.

If unused keep pin open.

6.5 Pin Assignment and Signal Description

Restrictions during SLEEP mode:

During SLEEP Mode the ADC is shut down temporarily (per default). Please make sure that during SLEEP Mode shutdown the ADCx_IN input voltage does not exceed ±0.3V. The input current (reverse feeding) may reach 3mA! If SLEEP Mode is activated there are three protection possibilities:

- Use an RC combination for current limitation. Advantages: Lowest current consumption at SLEEP Mode, small component count, high input resistance Disadvantages: Lower input resistance at Sleep Mode (100k only).

- Use the AT^SNFM=,1 command to enable the ADC supply continuously . Advantages: No additional component components needed. Disadvantages: Higher current consumption in SLEEP (about 2mA)

- Detect presence of VMIC-voltage. If VMIC is off, make sure that ADCx_IN input voltages does not exceed ±0.3V Advantages: Lowest current, high input resistance. Disadvantages: Effort for SLEEP Mode (VMIC) detection.

7.2 Mounting XT65/XT75 to the Application Platform

There are many ways to properly install XT65/XT75 in the host device. An efficient approach is to mount the XT65/XT75 PCB to a frame, plate, rack or chassis.

Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or brackets. In addition, the board-to-board connection can also be utilized to achieve better support. To help you find appropriate spacers a list of selected screws and distance sleeves for 3mm stacking height can be found in

Section 9.2.

When using the two small holes take care that the screws are inserted with the screw head on the bottom of the XT65/XT75 PCB. Screws for the large holes can be inserted from top or bottom.

For proper grounding it is strongly recommended to use large ground plane on the bottom of board in addition to the five GND pins of the board-to-board connector. The ground plane may also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape. Please take care that attached cooling elements do not touch the antenna pads on the module’s bottom side, as this may lead a short-circuit.

To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat against the host device.
