Power Supply
The power supply is one of the key issues in the design of a GSM terminal.
Due to the burst emission mode used in GSM / GPRS, the power supply must be able to deliver high current peaks in a short time. During the peaks, the ripple (Uripp) on the supply voltage must not exceed a certain limit (see Table 1 Power supply voltage).

1/8 of the time (around 577µs every 4.615ms for GSM /GPRS class 2), o
2/8 of the time (around 1154µs every 4.615ms for GSM /GPRS class 10) and o
The rise time is around 10µs.
• Is internally used to provide via several regulators, the VCC_2V8 and VCC_1V8, the power supply required for the base band signals.
Wireless CPU Quik Q2687 shielding case is the grounding. The ground plane has to be connected to the motherboard through a complete layer on the PCB.

(1): This value has to be maintained during the burst (with 2.0A Peak in GSM, GPRS or EGPRS mode)
(2): The maximum operating Voltage Stationary Wave Ratio (VSWR) is 2:1
When supplying the Wireless CPU from a battery, the total impedance (battery + protections + PCB) should be <150 mOhms.
Caution:
When the Wireless CPU is in Alarm mode, no voltage must be applied on any pin of the 100-pin connector except on BAT-RTC (pin 7) for RTC operation or ON/~OFF (pin
19) to power ON the Wireless CPU.
3.2.1
Power Consumption
Power consumption is dependent on the configuration used. It is for this reason that the following consumption values are given for each mode, RF band and type of software used (AT or Open AT™).
All the following information is given assuming a 50 Ω RF output.
The following consumption values were obtained by performing measurements on
Wireless CPU samples at a temperature of 25° C.
Three VBATT values are used to measure the consumption, VBATTmin (3.2V),
VBATTmax (4.5V) and VBATTtyp (3.6V).
The average current is given for the three VBATT values and the peak current given is the maximum current peak measured with the three VBATT voltages.
For a more detailed description of the operating modes, see the Appendix of the AT
Command Interface Guide OS 6.61 [4]
For more information about the consumption measurement procedure, see Wireless
CPU Quik Q2687 Customer Design Guidelines [2].
3.2.1.1
Power Consumption without Open AT ® Processing

Main Serial Link (UART1)
A flexible 6-wire serial interface is available, complies with V24 protocol signaling, but not with V28 (electrical interface) due to a 2.8-Volt interface.
The signals are as follows:
• TX data (CT103/TX)
• RX data (CT104/RX)
• Request To Send (~CT105/RTS)
• Clear To Send (~CT106/CTS)
• Data Terminal Ready (~CT108-2/DTR)
• Data Set Ready (~CT107/DSR).
The set of RS-232 signals may be required for GSM DATA services application and is generated by the General Purpose I/O provided by the Wireless CPU Quik Q2687.
The two additional signals are:
• Data Carrier Detect (~CT109/DCD) and
• Ring Indicator (CT125/RI).

Common microphone input characteristics
The connection may be either differential or single-ended but use of a differential connection in order to reject common mode noise and TDMA noise is strongly recommended . When using a single-ended connection, be sure to have a good ground plane, good filtering and also shielding, in order to avoid any disturbance on the audio path.
The gain of the MIC inputs is internally adjusted and may be tuned using an AT command.
Both may be configured either as differential or single-ended.

Battery Charging Interface
The Wireless CPU Quik Q2687 supports one battery charging circuit, two algorithms and one hardware charging mode (pre-charging) for 3 battery technologies:
¾ Ni-Cd (Nickel-Cadmium) with algorithm 0
¾ Ni-Mh (Nickel-Metal Hydride) with algorithm 0
¾ Li-Ion (Lithium-Ion) with algorithm 1
The two algorithms control a switch, which connects the CHG-IN signal to the
VBATT signal. The algorithm controls the frequency and the connected time of the switch. During the charging procedure, battery charging level is controlled and when the Li-Ion algorithm is used, battery temperature is monitored via the BAT-TEMP ADC input.
One more charging procedure is available in the Q2687 Wireless CPU. This is called
"Pre-charging" mode, but is a special charging mode as it is activated only when the
Wireless CPU is OFF. Control is thus performed by the hardware. The purpose of this charging mode is to avoid battery damage by preventing the battery from being discharged to below the minimum battery level.
3.16.1
Ni-Cd / Ni-Mh Charging Algorithm
To charge the battery, the algorithm measures battery level when the switch is open
(T2) and charges the battery by closing the switch (T3). When the battery is charged
(battery voltage reaches BattLevelMax) the switch is open for time T3.

Li-Ion Charging Algorithm
The Li-Ion algorithm provides battery temperature monitoring, which is highly recommended to prevent battery damage during the charging phase.
The Li-Ion charger algorithm may be configured into three phases:
1.
Constant charge
2.
Start of pulse charge
3.
End of pulse charge
The three phases can be seen in the following waveform diagram for full-charging:

Controlled Pre-charging Hardware
The pre-charging mode which is hardware controlled (but not the software controlled) is also available. This mode is only activated when the Wireless CPU is
OFF and when VBATT is in the voltage range of 2.8V < VBATT < 3.2V. The charger power supply must be connected to CHG-IN (pin 6,8). In pre-charging mode, the battery is charged with a direct current of 50mA. The FLASH-LED blinks, when this mode is activated.
This mode is not a real charging mode as it is not possible to obtain a full charge with it, but it is useful to save the battery life by preventing the battery from being discharged to below the low limit voltage value.
3.16.4
Temperature Monitoring
Temperature monitoring is only available for the Li-Ion battery with algorithm 1. The
BAT-TEMP (pin 20) ADC input must be used to sample the temperature analog signal provided by an NTC temperature sensor. The minimum and maximum temperature range may be set by AT command.

ON / ~OFF Signal
This input is used to switch the Wireless CPU Quik Q2687 ON or OFF.
A high-level signal must be provided on the ON/~OFF pin to switch ON the Wireless
CPU. The voltage of this signal must be maintained for a minimum of 3000ms. This signal may be left at high level until it is switched off.
To switch OFF the Wireless CPU, the ON/OFF pin must be released. The Wireless
CPU may be switched off via the Operating System.

Operating Sequences
3.17.1.1
Power ON
Once the Wireless CPU is supplied, the application must set the ON/OFF signal to high to start the Wireless CPU power ON sequence. The ON/OFF signal must be held for 3000ms minimum. After this period, an internal mechanism keeps it on hold.
During the power ON sequence, an internal reset is automatically performed by the
Wireless CPU for 40ms (typical). During this phase, any external reset should be avoided. Once initialization is complete (timing is SIM- and network-dependent), the
AT interface answers "OK" to the application. For further details, please check the AT
Commands Interface Guide.

Reset Signal (~RESET)
This signal is used to force a reset procedure by providing low level for at least 200µs.
This signal must be considered as an emergency reset only. A reset procedure is already driven by the internal hardware during the power-up sequence.
This signal may also be used to provide a reset to an external device (at power up only). If no external reset is necessary, this input may be left open. If used
(emergency reset), it must be driven either by an open collector or an open drain.
The Wireless CPU remains in reset mode as long as the ~RESET signal is held low.
Caution
This signal should only be used for "emergency" resets.
An Operating System reset is preferred to a hardware reset.
Reset sequence:
To activate the "emergency" reset sequence, the ~RESET signal has to be set to low for 200 µ s minimum. Once the reset is completed, the AT interface answers "OK" to the application.

At power-up, the ~RESET time (Rt) is carried out after switching ON the Wireless
CPU. It is generated by the internal voltage supervisor.
The ~RESET time is provided by the internal RC component. In order to keep the same time, avoid connecting another R or C component on the ~RESET signal. Only a switch or an open drain gate is recommended.
Ct is the cancellation time required for Wireless CPU initialization. Ct is automatically carried out by after hardware reset.

Digital Audio Interface (PCM)
Digital audio interface (PCM) mode allows connectivity with audio standard peripherals. It may be used, for example, to connect an external audio codec.
The programmability of this mode allows to address a large range of audio peripherals.
PCM features:
• IOM-2 compatible device on physical level
• Master mode only with 6 slots by frame, user only on slot 0
• Bit rate single clock mode at 768KHz only
• 16 bits data word MSB first only
• Linear Law only (no compression law)
• Long Frame Synchronization only
• Push-pull configuration on PCM-OUT and PCM-IN
The digital audio interface configuration cannot differ from the above specified features.
3.24.1
Description
The PCM interface consists of 4 wires:
• PCM-SYNC (output): The frame synchronization signal delivers an 8KHz frequency pulse that synchronizes the frame data in and the frame data out.
• PCM-CLK (output): The frame bit clock signal controls data transfer with the audio peripheral.
• PCM-OUT (output): The frame "data out" relies on the selected configuration mode.
• PCM-IN (input): The frame "data in" relies on the selected configuration mode.

Design Guidelines
6 Design Guidelines
The purpose of the following paragraphs is to give design guidelines.
6.1
Hardware and RF
6.1.1
EMC Recommendations
The EMC tests must be performed on the application as soon as possible to detect any potential problems.
When designing, special attention should be paid to:
• Possible spurious emission radiated by the application to the RF receiver in the receiver band
• ESD protection is mandatory on all signals which have external accessibility
(typically human accessibility). See Q2687 Wireless CPU Customer Design
Guidelines WM_DEV_Q2687_PTS_007 [2] for ESD protection samples. o
Similarly, ESD protection is mandatory for the:
SIM (if accessible from outside)
Serial link
• EMC protection on audio input/output (filters against 900MHz emissions)
• Biasing of the microphone inputs
• Length of the SIM interface lines (preferably <10cm)
• Ground plane: Wavecom recommends a common ground plane for analog/digital/RF grounds.
• A metallic case or plastic casing with conductive paint are recommended
Note:
The Wireless CPU does not include any protection against over-voltage.
6.1.2
Power Supply
The power supply is one of the key issues in the design of a GSM terminal.
A weak power supply design could, in particular, affect:
• EMC performance
• The emission spectrum
• The phase error and frequency error

WA_ENG_Q2687_PTS_001-002 September 11, 2006
Wireless CPU Quik Q2687
Design Guidelines
Warning:
Careful attention should be paid to:
The quality of the power supply: low ripple, PFM or PSM systems should be avoided
(PWM converter preferred).
Capacity to deliver high current peaks in a short time (pulsed radio emission).

Wireless CPU Quik Q2687
Design Guidelines
6.1.4
Antenna
Warning:
Wavecom strongly recommends to work with an antenna manufacturer either to develop an antenna adapted to the application or to adapt an existing solution to the application.
Both the mechanical and electrical antenna adaptation are one of the key issues in the design of GSM terminal.
6.2
Mechanical Integration
Attention should be paid to:
• Antenna cable integration (bending, length, position, etc)
• Leads of the Wireless CPU to be soldered to the Ground plane
6.3
Operating System Upgrade
The Wireless CPU Quik Q2687 Operating System is stored in flash memory and may easily be upgraded.
IMPORTANT:
In order to follow regular changes in the GPRS standard and to offer a state-of-the-art
Operating System, Wavecom recommends that the application designed around a
WISMO (or WISMO based product) allow easy Operating System upgrades on the
Wireless CPU via the standard Xmodem protocol. Therefore, the application shall either allow a direct access to the WISMO serial link through an external connector or implement any mechanism allowing the WISMO Operating System to be downloaded via Xmodem.
The Operating System file may be downloaded to the Wireless CPU using the
Xmodem protocol. The AT+WDWL command allows the download process to be launched (see the description in the AT Command User Guide).
The serial signals required to proceed with Xmodem downloading are:
Rx, Tx, RTS, CTS and GND.
The Operating System file may also be downloaded to the Wireless CPU using the
DOTA (download over the air) feature. This feature is available with the Open AT interface. For more details, please, refer to the Open AT ® documentation.

Your GSM terminal is actually a low power radio transmitter and receiver. It sends out as well as receives radio frequency energy. When you use your GSM application, the cellular system which handles your calls controls both the radio frequency and the power level of your cellular modem.

Exposure to RF energy
There has been some public concern about possible health effects of using GSM terminals. Although research on health effects from RF energy has focused on the current RF technology for many years, scientists have begun research regarding newer radio technologies, such as GSM. After existing research had been reviewed, and after compliance to all applicable safety standards had been tested, it has been concluded that the product was fitted for use.
If you are concerned about exposure to RF energy there are things you can do to minimize exposure. Obviously, limiting the duration of your calls will reduce your

Appendix exposure to RF energy. In addition, you can reduce RF exposure by operating your cellular terminal efficiently by following the guidelines below.
7.2.1.3
Efficient Terminal Operation
For your GSM terminal to operate at the lowest power level, consistent with satisfactory call quality:
If your terminal has an extendable antenna, extend it fully. Some models allow you to place a call with the antenna retracted. However, your GSM terminal operates more efficiently with the antenna when it is fully extended.
Do not hold the antenna when the terminal is "IN USE". Holding the antenna affects call quality and may cause the modem to operate at a higher power level than needed.
7.2.1.4
Antenna Care and Replacement
Do not use the GSM terminal with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Replace the damaged antenna immediately. You may repair antenna yourself by following the instruction manual provided to you. If so, use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by a qualified technician.
Buy or replace the antenna only from the approved suppliers list. Using of unauthorized antennas, modifications or attachments could damage the terminal and may violate local RF emission regulations or invalidate type approval.

General Safety
7.2.2.1
Driving
Check the laws and the regulations regarding the use of cellular devices in the area where you have to drive, as you always have to comply with them. When using your
GSM terminal while driving, please:
• give full attention to driving,
• pull-off the road and park before making or answering a call (if driving conditions so require).
7.2.2.2
Electronic Devices
Most electronic equipments, for example in hospitals and motor vehicles are shielded from RF energy. However, RF energy may affect some improperly shielded electronic equipment.

7.2.2.3
Vehicle Electronic Equipment
Check your vehicle manufacturer representative to determine if any on-board electronic equipment is adequately shielded from RF energy.
7.2.2.4
Medical Electronic Equipment
Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc...) to determine if they are adequately shielded from external RF energy.
Turn your terminal OFF in health care facilities when any regulations posted in the area instruct you to do so. Hospitals or health care facilities may be using RF monitoring equipment.
7.2.2.5
Aircraft
Turn your terminal OFF before boarding any aircraft.
• Use it on the ground only with crew permission.
• Do not use it in the air.
To prevent possible interference with aircraft systems, Federal Aviation
Administration (FAA) regulations require you to have prior permission from the crew members to use your terminal while the aircraft is on the ground. In order to prevent interference with cellular systems, local RF regulations prohibit using your modem, while airborne.
7.2.2.6
Children
Do not allow children to play with your GSM terminal. It is not a toy. Children could hurt themselves or others (by poking themselves or others in the eye with the antenna, for example). Children could damage the modem, or make calls that increase your modem bills.
7.2.2.7
Blasting Areas
To avoid interfering with blasting operations, turn your unit OFF when in a "blasting area" or in areas posted: "turn off two-way radio". Construction crew often uses remote control RF devices to set off explosives .
7.2.2.8
Potentially Explosive Atmospheres
Turn your terminal OFF when in any area with a potentially explosive atmosphere. It is rare, but your modem or its accessories could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injuries or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fuelling areas such as petrol stations; below decks on boats;

Appendix fuel or chemical transfer or storage facilities; and areas where the air contains chemicals or particles, such as grain, dust, or metal powders.
Do not transport or store flammable gas, liquid, or explosives, in the compartment of your vehicle which contains your terminal or accessories.
Before using your terminal in a vehicle powered by liquefied petroleum gas (such as propane or butane) ensure that the vehicle complies with the relevant fire and safety regulations of the country in which the vehicle is to be used.
