3.2 Power Supply

3.2.1 Power Supply Description

The power supply required for the Q52Omni is a dual rail supply; VCC_3V6 and VCC_12V. VCC_12V is only required to support Satellite mode operation. VCC_3V6 is used for GSM/GPRS, Satellite and GPS operation.

The power supply is one of the key issues in the design of a dual mode terminal. Operation in GSM mode requires particularly careful attention to the ability of the power supply to provide clean DC power.

Due to the burst emission mode used in GSM/GPRS, the VCC_3V6 power supply must be able to deliver high current peaks in a short time. During the peaks, the ripple (U Power Supply Voltage

• In communication mode, a GSM/GPRS class 2 terminal emits 577μs radio

) on the supply voltage must not exceed a certain limit (see Table 3:

bursts every 4.615ms (see

• In communication mode, a GPRS class 10 terminal emits 1154μs radio bursts every 4.615ms.

Only the VCC_3V6 (+3.6 VDC) power supply input is necessary during GSM mode of operation

VCC_3V6:

• Supplies the GSM RF components. It is essential to keep a minimum voltage ripple at this connection in order to avoid any phase error.

The RF Power Amplifier current (2.0 A peak in GSM /GPRS mode) flows with a ratio of:

• 1/8 of the time (around 577μs every 4.615ms for GSM /GPRS cl. 2) and

• 2/8 of the time (around 1154μs every 4.615ms for GSM /GPRS

cl. 10).

The rise time is around 10μs.

3.10 Analog Audio Interface

The Q52 OMNI provides a single ended microphone input and single ended speaker output for GSM audio I/O. An echo cancellation feature allows hands free functionality in GSM voice mode.

3.10.1 Microphone Input

3.10.1.1 Features

The MIC input includes the biasing for an electret microphone, thus allowing easy connection. The gain of the MIC input is internally adjusted and may be tuned using an AT command. AC coupling is already embedded in the Q52 Omni.

When you design the audio analog interface be sure to have a very good ground plane, a very good filtering as well as shielding in order to avoid any disturbance on the audio path.

4.7 μF < C1 < 47 μF (depending on speaker characteristics and output power).

The connection between the Q52 Omni pin and the speaker must be designed to keep the serial impedance lower than 1.5 Ω in single ended mode.

3.10.3 Design Recommendation

3.10.3.1 General

When speakers and microphones are exposed to the external environment, it is recommended to add ESD protection as closed as possible to the speaker or microphone, connected between the audio lines and a good ground.

You ensure to have a good ground plane, a good filtering as well as shielding, in order to avoid any disturbance on the audio path.

It is important to select an appropriate microphone, speaker and filtering components to avoid TDMA noise

3.10.3.2 Recommended Microphone Characteristics

• The impedance of the microphone has to be around 2 kΩ.

• Sensitivity from -40dB to –50 dB.

• SNR > 50 dB.

• Frequency response compatible with the GSM specifications.

To suppress TDMA noise, it is highly recommended to use microphones with two internal decoupling capacitors:

-CM1=56pF (0402 package) for the TDMA noise coming from the demodulation of the GSM 850 and GSM900 frequency signal.

-CM2=15pF (0402 package) for the TDMA noise coming from the demodulation of the DCS/PCS frequency signal.

The capacitors have to be soldered in parallel of the microphone

3.10.3.3 Recommended Speaker Characteristics

• Type of speakers: Electro-magnetic /10mW

• Impedance: 8Ω for hands-free (SPK2)

• Sensitivity: 110dB SPL min

• Receiver frequency response compatible with the GSM specifications.

3.10.3.4 Recommended Filtering Components

When designing a GSM application, it is important to select the right audio filtering components.

The strongest noise, called TDMA, is mainly due to the demodulation of the GSM850/GSM900/DCS1800 and PCS1900 signal: A burst being produced every

4.615ms; the frequency of the TDMA signal is equal to 216.7Hz plus harmonics.

The TDMA noise can be suppress by filtering the RF signal using the right decoupling components.

The types of filtering components are:

-RF decoupling inductors

-RF decoupling capacitors

A good “Chip S-Parameter” simulator is proposed by Murata, the following link help to find it:

http://www.murata.com/designlib/mcsil.html

Using different Murata components, we could see that the value, the package and the current rating can have different decoupling effects.

Q52 Omni Product

Technical Specification

The duration of the firmware power-up sequence depends on:

• The need to perform a recovery sequence if the power has been lost during a flash memory modification.

Other factors have a minor influence

• the number of parameters stored in EEPROM by the AT commands received so far

• the ageing of the hardware components, especially the flash memory

• the temperature conditions

The

recommended

way to de-assert the ~ON/OFF signal is to use either an AT command or WIND indicators: the application has to detect the end of the powerup initialization and de-assert ~ON/OFF afterwards.

• Send an “AT” command and wait for the “OK” answer: once the initialization is

complete the AT interface answers « OK » to “AT” message

• Wait for the “+WIND: 3” message: after initialization, the Q52 OMNI /Open AT

Software Suite v2.0, if configured to do so, will return an unsolicited “+WIND: 3” message. The generation of this message is enabled or disabled via an AT command.

Note:

• Please refer to the document Firmware v7.0

0 for more information on these commands.

[3] AT Command Interface Guide for Open AT®

Proceeding thus – by software detection - will always prevent the application from de-asserting the ~ON/OFF signal too early.

If WIND indicators are disabled or AT commands unavailable or not used, it is still possible to de-assert ~ON/OFF after a delay long enough (T

on/off-hold

) to ensure that

the firmware has already completed its power-up initialization.

The table below gives the minimum values of T

Open AT® Firmware

power-up time

The above figure take the worst cases into account: power-loss recovery operations, slow flash memory operations in high temperature conditions, and so on. But they are safe because they are large enough to ensure that ~ON/OFF is not de-asserted too early.

Additional notes:

If the application manages hardware flow control, the AT command can be sent during the

initialisation phase.

Page 52 / 78

Q52 Omni Product

Technical Specification

1. Typical power-up initialization time figures for best cases conditions (no

power-loss recovery, fast and new flash memory…) approximate 3.5 seconds in every firmware version. But releasing ~ON/OFF after this delay does not guarantee that the application will actually start-up if for example the power plug has been pulled off during a flash memory operation, like a phone book entry update or an AT&W command…

2. The ~ON/OFF signal can be left at a low level until switch OFF. But this is

not recommended as it will prevent the AT+CPOF command from performing a clean power-off. (See also the note in the

Power OFF chapter

for an alternate usage.)

3. When using a battery as power source, it is not recommended to let this

signal high:

If the battery voltage is too low and the ~ON/OFF signal at high level, an internal mechanism switches OFF the Q52 OMNI /Open AT

Software Suite v1.0. This automatic process prevents the battery to be over discharged and optimize its life span.

4. During the power-ON sequence, an internal reset is automatically performed by the Q52 OMNI /Open AT

Software Suite v2.0 for 40 ms

(typically). Any external reset should be avoided during this phase.

5. After a reset (hardware or software), if the ~ON/OFF signal is OFF (High level) the Q52 OMNI switches OFF.

5.3 Safety Recommendations (for Information Only)

IMPORTANT

FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM APPLICATION

PLEASE READ THIS INFORMATION CAREFULLY

5.3.1 RF Safety

5.3.1.1 General

Your GSM terminal GSM standard is spread all over the world. It covers Europe, Asia and some parts of America and Africa. This is the most used telecommunication standard.

Your GSM terminal is actually a low power radio transmitter and receiver. It sends out and 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.

is based on the GSM standard for cellular technology. The

5.3.1.2 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 exposure to RF energy. In addition, you can reduce RF exposure by operating your cellular terminal efficiently by following the guidelines below.

5.3.1.3 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 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.

based on WISMO2D

Q52 Omni Product

Technical Specification

5.3.1.4 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 a damaged antenna immediately. Consult your manual to see if you may change the antenna yourself. If so, use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by a qualified technician.

Use only the supplied or approved antenna. Unauthorized antennas, modifications or attachments could damage the terminal and may contravene local RF emission regulations or invalidate type approval.

5.3.2 General Safety

5.3.2.1 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.

5.3.2.2 Electronic Devices

Most electronic equipment, for example in hospitals and motor vehicles is shielded from RF energy. However RF energy may affect some improperly shielded electronic equipment.

5.3.2.3 Vehicle Electronic Equipment

Check your vehicle manufacturer representative to determine if any on-board electronic equipment is adequately shielded from RF energy.

5.3.2.4 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.

5.3.2.5 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.

agreement.

Page 77 / 78

Q52 Omni Product

Technical Specification

To prevent possible interference with aircraft systems, Federal Aviation Administration (FAA) regulations require you to have permission from a crew member to use your terminal while the aircraft is on the ground. To prevent interference with cellular systems, local RF regulations prohibit using your modem while airborne.

5.3.2.6 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.

5.3.2.7 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.

5.3.2.8 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 fueling areas such as petrol stations; below decks on boats; 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.
