4.2.2. GC864-QUAD V2 Antenna Connector

The GC864-QUAD V2 module is equipped with a 50 ohm RF connector from Murata, GSC type P/N MM9329-2700B. The counterpart suitable is Murata MXTK92 Type or MXTK88 Type.

Moreover, the GC864-QUAD V2 has the antenna pads on the back side of the PCB. This allows the manual soldering of the coaxial cable directly on the back side of the PCB. However, the soldering is not an advisable solution for a reliable connection of the antenna.

5. Hardware Commands

5.1. Turning ON the GE/GC864-QUAD V2 and GE864-

GPS

To turn ON the GE/GC864-QUAD V2 AND GE864-GPS the pad ON# must be tied low for at least 1 second and then released. Pulse duration less than 1000ms should also start the power on procedure, but this is not guaranteed.

When the power supply voltage is lower than 3.4V the pad ON# must be tied low for at least 4 seconds.

The maximum current that can be drained from the ON# pad is

0.1 mA. A simple circuit to do it is:

NOTE:

Don't use any pull up resistor on the ON# line, it is internally pulled up. Using pull up resistor may bring to latch up problems on the module, power regulator and improper power on/off of the module. The line ON# must be connected only in open collector configuration.

NOTE:

In this document all the lines that are inverted, hence have active low signals are labeled with a name that ends with a "#".

Page 27

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

TIP:

To check if the device has powered on, the hardware line PWRMON should be monitored. After 1000ms the line raised up the device could be considered powered on.

NOTE: When the power supply voltage is lower than 3.4V, to turn ON the module, the pad ON# must be tied low for at least 3 seconds.

For example: 1- Let us assume you need to drive the ON# pad with a totem

pole output from +1.8V up to 5V microcontroller:

2- Let us assume you need to drive the ON# pad directly with an

ON/OFF button:

A flow chart showing the proper turn on procedure is displayed below:

Page 29

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

NOTE:

In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when is powered OFF or during an ON/OFF transition.

A flow chart showing the AT commands managing procedure is displayed below:

Page 30

1vv0300915 Rev.2 – 2011-06-15

5.2. Turning OFF the GE/GC864-QUAD V2 and GE864

GPS

The turning off of the device can be done in two ways:

• via AT command (see Software User Guide AT#SHDN)

• by tying low pin ON#

Either ways, when the device issues a detach request to the network informing that the device will not be reachable any more.

To turn OFF the module the pad ON# must be tied low for at least 2 seconds and then released.

The same circuitry and timing for the power on shall be used. The device shuts down after the release of the ON# pad. The following flow chart shows the proper turnoff procedure:

Page 31

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

TIP: To check if the device has been powered off, the hardware line

PWRMON must be monitored. The device is powered off when PWRMON goes low.

NOTE:

In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when is powered OFF or during an ON/OFF transition.

1vv0300915 Rev.2 – 2011-06-15

5.3. Hardware Unconditional Restart

WARNING:

The hardware unconditional Restart must not be used during normal operation of the device since it does not detach the device from the network. It shall be kept as an emergency exit procedure to be done in the rare case that the device gets stacked waiting for some network or SIM responses.

To unconditionally restart the module, the pad RESET# must be tied low for at least 200 milliseconds and then released.

The maximum current that can be drained from the RESET# pad is

0.15 mA. A simple circuit to do it is:

NOTE:

Do not use any pull up resistor on the RESET# line or any totem pole digital output. Using pull up resistor may bring to latch up problems on the module power regulator and improper functioning of the module. The line RESET# must be connected only in open collector configuration.

Page 33

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

TIP:

The unconditional hardware Restart must always be implemented on the boards and must be used by the software as an emergency exit procedure.

The following flow chart shows the proper RESET procedure:

NOTE:

In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when is powered OFF or during an ON/OFF transition.

For example:

Page 34

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

Let us assume you need to drive the RESET# pad with a totem pole output from +1.8V up to 5V microcontroller

This signal is internally pulled up so the pin can be left floating if not used.

5.4. Turning ON/OFF the GPS (only GE864-GPS)

When GPS is not in GSM controlled mode (controlled by GSM) a specific sequence to power-up and shutdown it’s needed.

5.4.1. GPS Power-up

After you first apply power the GPS part of GE864-GPS goes into a low-power mode status. To switch ON the GPS part is requested a pulse at the input pin GPS_ON_OFF. In order to know when the GPS is ready to accept the pulse, the application in the host controller can either:

- Wait for a fixed interval

- Monitor a pulse on GPS_WAKEUP output

Page 35

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

- Assert a pulse on the GPS_ON_OFF input every seconds

until GPS starts indicating a high on GPS_WAKEUP output or generation of serial messages.

The GPS starts after asserting a rising edge pulse on GPS_ON_OFF input and when high level persists for at least three cycles of RTC clock. Before asserting another pulse to GPS_ON_OFF input, the host controller must put it at low state and hold it low for at least three cycles of the RTC clock.

The GPS_WAKEUP output goes high indicating the GPS is working. As suggested in chapter 4.1.1 (Pin Out) do not leave the

GPS_ON_OFF (ball J4) input pin floating. It’ suggested to connect it to a pull-down resistor (e.g.: 100k)

5.4.2. GPS Shutdown

1vv0300915 Rev.2 – 2011-06-15

When GPS is working, a pulse on the GPS_ON_OFF input origins the GPS shutdown sequence.

As explained for power-up, a rising edge pulse followed by an high level logic for at least three cycles of RTC clock is recognized as an GPS_ON_OFF pulse. Before asserting another pulse to GPS_ON_OFF input, the host controller must put it at low state and hold it low for at least three cycles of the RTC clock.

The shutdown sequence may take anywhere from 10ms to 900ms, depending on operation in progress.

Avoid any abrupt, uncontrolled removal of power (VBATT) while GPS is operating. Before removing the supply from the module, perform the shutdown sequence. Performance degradation may be the consequences of any uncontrolled removal of main power.

1vv0300915 Rev.2 – 2011-06-15

The GSM system is made in a way that the RF transmission is not continuous, else it is packed into bursts at a base frequency of about 216 Hz, the relative current peaks can be as high as about 2A. Therefore the power supply has to be designed in order to withstand with these current peaks without big voltage drops; this means that both the electrical design and the board layout must be designed for this current flow. If the layout of the PCB is not well designed a strong noise floor is generated on the ground and the supply; this will reflect on all the audio paths producing an audible annoying noise at 216 Hz; if the voltage drop during the peak current absorption is too much, then the device may even shutdown as a consequence of the supply voltage drop.

TIP:

The electrical design for the Power supply should be made ensuring it will be capable of a peak current output of at least 2A.

6.3. General Design Rules

The principal guidelines for the Power Supply Design embrace three different design steps:

• the electrical design

• the thermal design

• the PCB layout.

6.3.1. Electrical Design Guidelines

The electrical design of the power supply depends strongly from the power source where this power is drained. We will distinguish them into three categories:

• +5V input (typically PC internal regulator output)

• +12V input (typically automotive)

• Battery

6.3.1.1. +5V input Source Power Supply Design Guidelines

• The desired output for the power supply is 3.8V, hence

there is no big difference between the input source and the desired output. A linear regulator can be used. A switching power supply will not be suited because of the low drop out requirements.

Page 39

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

• When using a linear regulator, a proper heat sink

shall be provided in order to dissipate the power generated.

• A Bypass low ESR capacitor of adequate capacity must

be provided in order to cut the current absorption peaks close to the module, a 100µF tantalum capacitor

is usually suited.

• Make sure the low ESR capacitor on the power supply

output (usually a tantalum one) is rated at least 10V.

• A protection diode can be inserted close to the power

input, in order to save the module from power polarity inversion.

An example of linear regulator with 5V input is:

6.3.1.2. +12V input Source Power Supply Design Guidelines

• The desired output for the power supply is 3.8V,

hence, due to the big difference between the input source and the desired output, a linear regulator is not suited and shall not be used. A switching power supply will be preferable because of its better

Page 40

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

efficiency especially with the 2A peak current load represented by the module.

• When using a switching regulator, a 500kHz (or more)

switching frequency regulator is preferable, because of its smaller inductor size and its faster transient response. This allows the regulator to respond quickly to the current peaks absorption.

• In any case the frequency and switching design

selection is related to the application to be developed, due to the fact that the switching frequency could also generate EMC interferences.

• As far as car PB battery, the input voltage can rise

up to 15.8V. This must be kept in mind when choosing components: all components in the power supply must withstand this voltage.

• A Bypass low ESR capacitor of adequate capacity must

be provided, in order to cut the current absorption peaks. A 100µF tantalum capacitor is typically used.

• Make sure the low ESR capacitor on the power supply

output (usually a tantalum one) is rated at least 10V.

• As far as car applications, a spike protection diode

must be inserted close to the power input, in order to clean the supply from spikes.

• A protection diode can be inserted close to the power

input, in order to save the module from power polarity inversion. This can be the same diode used for spike protection.

An example of switching regulator with 12V input is in the schematic below (split in 2 parts):

Page 41

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

6.3.1.3. Battery Source Power Supply Design Guidelines

• The desired nominal output for the power supply is 3.8V

and the maximum voltage allowed is 4.2V, hence a single

3.7V Li-Ion cell battery type is suited for supplying the power to the Telit GE/GC864-QUAD V2 AND GE864-GPSmodules.

The three cells Ni/Cd or Ni/MH 3,6 V Nom. battery types or 4V PB types MUST NOT BE USED DIRECTLY since their maximum voltage can rise over the absolute maximum voltage for the module and damage it.

Page 42

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

WARNING:

DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly connected with GE/GC864-QUAD V2 and GE864-GPS. Their use can lead to overvoltage on the module and damage it. USE ONLY Li-Ion battery types.

• A Bypass low ESR capacitor of adequate capacity must be

provided in order to cut the current absorption peaks, a 100µF tantalum capacitor is usually suited.

• Make sure the low ESR capacitor (usually a tantalum one)

is rated at least 10V.

• A protection diode should be inserted close to the power

input, in order to save the module from power polarity inversion. Otherwise the battery connector should be done in a way to avoid polarity inversions when connecting the battery.

• The battery capacity must be at least 500mAh in order to

withstand the current peaks of 2A; the suggested capacity is from 500mAh to 1000mAh.

6.3.2. Thermal Design Guidelines

The thermal design for the power supply heat sink must be done with the following specifications:

• Average current consumption during transmission @PWR

level max: 500mA

• Average current consumption during transmission @ PWR

level min: 100mA

• Average current during Power Saving (CFUN=5): from 1.5 to

3.9mA

• Average current during idle (Power Saving disabled): 16mA

NOTE:

The average consumption during transmissions depends on the power level at which the device is requested to transmit by the network. The average current consumption hence varies significantly.

Page 43

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

Considering the very low current during idle, especially if Power Saving function is enabled, it is possible to consider from the thermal point of view that the device absorbs current significantly only during calls.

If we assume that the device stays into transmission for short periods of time (let us say few minutes) and then remains for a quite long time in idle (let us say one hour), then the power supply has always the time to cool down between the calls, and the heat sink could be smaller than the calculated one for 500mA maximum RMS current, or even could be the simple chip package (no heat sink).

Moreover, in the average network conditions, the device is requested to transmit at a lower power level than the maximum, hence the current consumption will be less than 500mA, usually around 150mA.

For these reasons the thermal design is rarely a concern and the simple ground plane where the power supply chip is placed grants a good thermal condition to avoid overheating as well.

As far as the heat generated by GC/GE864-QUAD V2 and GE864-GPS , you can consider it to be during transmissions of 1W max during CSD/VOICE calls and 2W max during class10 GPRS upload.

This generated heat will be mostly conducted to the ground plane under GC/GE864-QUAD V2 AND GE864-GPS ; you must ensure that your application can dissipate it.

6.3.3. Power Supply PCB Layout Guidelines

As seen on the electrical design guidelines the power supply shall have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct working of the circuitry. A misplaced component can be useless or can even decrease the power supply performances.

• The Bypass low ESR capacitor must be placed close to the

Telit GE/GC864-QUAD V2 and GE864-GPS power input pads or in the case the power supply is a switching type it can be placed close to the inductor to cut the ripple provided the PCB trace from the capacitor to the GE/GC864-QUAD V2 and GE864-GPS wide enough to ensure a dropless connection even during the 2A current peaks.

• The protection diode must be placed close to the input

connector where the power source is drained.

• The PCB traces from the input connector to the power

regulator IC must be wide enough to ensure no voltage drops

Page 44

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

occur when the 2A current peaks are absorbed. Note that this is not made in order to save power loss but especially to avoid the voltage drops on the power line at the current peaks frequency of 216 Hz that will reflect on all the components connected to that supply, introducing the noise floor at the burst base frequency. For this reason while a voltage drop of 300-400 mV may be acceptable from the power loss point of view, the same voltage drop may not be acceptable from the noise point of view. If your application does not have audio interface but only uses the data feature of the Telit GE/GC864-QUAD V2 and GE864-GPSthen this noise is not so disturbing and power supply layout design can be more forgiving.

• The PCB traces to the GE/GC864-QUAD V2 and GE864-GPS and the

Bypass capacitor must be wide enough to ensure no significant voltage drops occur when the 2A current peaks are absorbed. This is for the same reason as previous point. Try to keep this trace as short as possible.

• The PCB traces connecting the Switching output to the

inductor and the switching diode must be kept as short as possible by placing the inductor and the diode very close to the power switching IC (only for switching power supply). This is done in order to reduce the radiated field (noise) at the switching frequency (100-500 kHz usually).

• The use of a good common ground plane is suggested.

• The placement of the power supply on the board must be done

in such a way to guarantee that the high current return paths in the ground plane are not overlapped to any noise sensitive circuitry as the microphone amplifier/buffer or earphone amplifier.

• The power supply input cables must be kept separate from

noise sensitive lines such as microphone/earphone cables.

6.3.4. Parameters for ATEX Applications

In order to integrate the Telit’s modules into an ATEX application, the appropriate reference standard IEC EN xx and integrations shall be followed.

7.1.2. GE864-QUAD V2/GPS GSM Antenna – PCB line

Guidelines

When using the Telit GE864-QUAD V2 or GE864-GPS module, since there's no antenna connector on the module, the antenna must be connected to the GE864-QUAD V2 or GE864-GPS through the PCB with the antenna pad.

In the case that the antenna is not directly developed on the same PCB, hence directly connected at the antenna pad of the GE864-QUAD V2 or GE864-GPS, then a PCB line is needed in order to connect with it or with its connector.

This line of transmission shall fulfill the following requirements:

50 ohm 0,3 dB

Attenuation

equipotential to the GE864-QUAD V2 ground pins

This transmission line should be designed according to the following guidelines:

• Ensure that the antenna line impedance is 50 ohm;

• Keep the antenna line on the PCB as short as possible,

since the antenna line loss shall be less than 0,3 dB;

• Antenna line must have uniform characteristics, constant

cross section, avoid meanders and abrupt curves;

• Keep, if possible, one layer of the PCB used only for the

Ground plane;

• Surround (on the sides, over and under) the antenna line

on PCB with Ground, avoid having other signal tracks facing directly the antenna line track;

• The ground around the antenna line on PCB has to be

strictly connected to the Ground Plane by placing vias once per 2mm at least;

Page 48

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

• Place EM noisy devices as far as possible from GE864-QUAD

V2 antenna line;

• Keep the antenna line far away from the GE864-QUAD V2 or

GE864-GPS power supply lines;

• If you have EM noisy devices around the PCB hosting the

GE864-QUAD V2 or GE864-GPS, such as fast switching ICs, take care of the shielding of the antenna line by burying it inside the layers of PCB and surround it with Ground planes, or shield it with a metal frame cover.

• If you don't have EM noisy devices around the PCB of

GE864-QUAD V2 or GE864-GPS, by using a strip-line on the superficial copper layer for the antenna line, the line attenuation will be lower than a buried one;

7.2. PCB Guidelines in case of FCC certification

In the case FCC certification is required for an application using GE864-QUAD V2 or GE864-GPS, according to FCC KDB 996369 for modular approval requirements, the transmission line has to be similar to that implemented on GE864-QUAD V2 or GE864-GPS interface board and described in the following chapter.

7.2.1. Transmission line design

During the design of the GE864-QUAD V2 or GE864-GPS interface board, the placement of components has been chosen properly, in order to keep the line length as short as possible, thus leading to lowest power losses possible. A Grounded Coplanar Waveguide (G-CPW) line has been chosen, since this kind of transmission line ensures good impedance control and can be implemented in an outer PCB layer as needed in this case. A SMA female connector has been used to feed the line. The interface board is realized on a FR4, 4-layers PCB. Substrate material is characterized by relative permittivity εr = 4.6 ± 0.4 @ 1 GHz, TanD= 0.019 ÷ 0.026 @ 1 GHz. A characteristic impedance of nearly 50 Ω is achieved using trace width = 1.1 mm, clearance from coplanar ground plane = 0.3 mm each side. The line uses reference ground plane on layer 3, while copper is removed from layer 2 underneath the line. Height of trace above ground plane is 1.335 mm. Calculated characteristic impedance is

51.6 Ω, estimated line loss is less than 0.1 dB. The line geometry is shown below:

7.2.3. GSM Antenna – Installation Guidelines

• Install the antenna in a place covered by the GSM

signal.

• The Antenna must be installed to provide a separation

distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter;

• Antenna shall not be installed inside metal cases

• Antenna shall be installed also according Antenna

manufacturer instructions.

7.3. GPS Antenna (GE864-GPS only)

7.3.1. GPS Antenna Requirements

The GE864-GPS module is provided with an internal LNA amplifier with two selectable gain level. By default the GE864-GPS is configured in high gain mode (18dB with 2dB of noise figure).

If the external antenna is connected to the DUT with a long coax cable, the use of an external LNA close to the antenna feed point is recommended. In this case the module must be configured in low gain mode (8dB with 10dB of noise figure) through a specific AT command (refer to AT$GPSAT on AT Commands Reference Guide, 80000ST10025a). The module provides a digital output signal (GPS_LNA_EN) used for RF power control that can be used to enable the external LNA.

NOTE: when the internal LNA is in high gain mode, the GPS_LNA_EN output is tied low (external LNA unused).

NOTE: The typical external gain range is 20 dB (when in low gain mode, not recommended in high gain mode)

Page 52

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

NOTE: The absolute maximum rating for GPS RF input power is 10 dBm

7.3.2. Combined GPS Antenna

The use of combined GPS antennas is NOT recommended; this solution could generate an extremely poor GPS reception and also the combination antenna requires additional diplexer and adds a loss in the RF route.

7.3.3. Linear and Patch GPS Antenna

Using this type of antenna introduces at least 3 dB of loss if compared to a circularly polarized (CP) antenna. Having a spherical gain response instead of a hemispherical gain response could aggravate the multipath behaviour & create poor position accuracy.

7.3.4. GPS Antenna - PCB Line Guidelines

• Ensure that the antenna line impedance is 50Ω.

• Keep the antenna line on the PCB as short as possible

to reduce the loss.

• Antenna line must have uniform characteristics,

constant cross section, avoid meanders and abrupt curves.

• Keep one layer of the PCB used only for the Ground

plane, if possible.

• Surround (on the sides, over and under) the antenna

line on PCB with Ground, avoid having other signal tracks facing directly the antenna line of track.

• The ground around the antenna line on PCB has to be

strictly connected to the Ground Plane by placing vias once per 2mm at least.

• Place EM noisy devices as far as possible from GE864-

GPS antenna line.

• Keep the antenna line far away from the GE864-GPS

power supply lines.

• Keep the antenna line far away from the GE864-GPS GSM

RF lines.

• If you have EM noisy devices around the PCB hosting

the GE864-GPS, such as fast switching ICs, take care of the shielding of the antenna line by burying it inside the layers of PCB and surround it with Ground planes, or shield it with a metal frame cover.

Page 53

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

• If you do not have EM noisy devices around the PCB of

GE864-GPS, use a strip-line on the superficial copper layer for the antenna line. The line attenuation will be lower than a buried one.

7.3.5. GPS Antenna - Installation Guidelines

• The GE864-GPS due to its characteristics of

sensitivity is capable to perform a Fix inside the buildings. (In any case the sensitivity could be affected by the building characteristics i.e. shielding).

• The Antenna must not be co-located or operating in

conjunction with any other antenna or transmitter.

• Antenna must not be installed inside metal cases.

• Antenna must be installed also according Antenna

manufacturer instructions.

8.1. Reset Signal

RESET Reset I A2 on GE864-QUAD

RESET is used to reset the GE/GC864-QUAD V2 and GE864-GPS modules. Whenever this signal is pulled low, the GE/GC864-QUAD V2 and GE864-GPS are reset. When the device is reset it stops any operation. After the release of the reset GE/GC864-QUAD V2 and GE864-GPS are unconditionally shut down, without doing any detach operation from the network where it is registered. This behavior is not a proper shut down because any GSM device is requested to issue a detach request on turn off. For this reason the Reset signal must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stuck waiting for some network response.

1vv0300915 Rev.2 – 2011-06-15

V2/GPS 54 on GC864-QUAD V2

The RESET is internally controlled on start-up to achieve always a proper power-on reset sequence, so there is no need to control this pin on start-up. It may only be used to reset a device already on that is not responding to any command.

NOTE:

Do not use this signal to power off GC/GE864-QUAD V2 and GE864-GPS . Use the ON/OFF signal to perform this function or the AT#SHDN command.

Reset Signal Operating Levels:

9. Serial Ports

The serial port on the Telit GE864/GC864-QUAD V2 and GE864-GPS is the core of the interface between the module and OEM hardware.

2 serial ports are available on the GE864-QUAD/GC864-QUAD V2 modules:

• MODEM SERIAL PORT (Main, ASC0)

• MODEM SERIAL PORT 2 (Auxiliary, ASC1)

While another serial port is available on the GE864-QUAD V2/GPS module:

• GPS SERIAL PORT (NMEA)

1vv0300915 Rev.2 – 2011-06-15

9.1. MODEM SERIAL PORT

Several configurations can be designed for the serial port on the OEM hardware, but the most common are:

• RS232 PC com port

• microcontroller UART @ 2.8V – 3V (Universal

Asynchronous Receive Transmit)

• microcontroller UART@ 5V or other voltages different

from 2.8V

Depending from the type of serial port on the OEM hardware a level translator circuit may be needed to make the system work. The only configuration that does not need a level translation is the 2.8V UART.

The serial port on the GE/GC864-QUAD V2 and GE864-GPS a +2.8V UART with all the 7 RS232 signals. It differs from the PCRS232 in the signal polarity (RS232 is reversed) and levels. The levels for the GE864-QUAD V2 UART are the CMOS levels:

application side, therefore on the GE/GC864-QUAD V2 AND GE864-GPSside these signal are on the opposite direction: TXD on the application side will be connected to the receive line (here named TXD/RX_uart ) of the GE/GC864-QUAD V2 AND GE864GPSserial port and viceversa for RX

TIP:

For a minimum implementation, only the TXD and RXD lines can be connected, the other lines can be left open provided a software flow control is implemented.

NOTE:

In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when is powered OFF or during an ON/OFF transition.

GPS RX Lines and TX lines may need a dual supply isolation buffer like an FXLP34 to avoid CMOS high states while in POWER SAVING.

9.3. RS232 Level Translation

In order to interface the Telit GE/GC864-QUAD V2 AND GE864GPSwith a PC com port or a RS232 (EIA/TIA-232) application a level translator is required. This level translator must

• invert the electrical signal in both directions

• change the level from 0/+3V to +15/-15V

Actually, the RS232 UART 16450, 16550, 16650 & 16750 chipsets accept signals with lower levels on the RS232 side (EIA/TIA-

562), allowing for a lower voltage-multiplying ratio on the level translator. Note that the negative signal voltage must be less than 0V and hence some sort of level translation is always required.

The simplest way to translate the levels and invert the signal is by using a single chip level translator. There are a multitude of them, differing in the number of driver and receiver and in the levels (be sure to get a true RS232 level translator not a RS485 or other standards).

Page 62

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

By convention the driver is the level translator from the 0/+3V UART level to the RS232 level, while the receiver is the translator from RS232 level to 0/+3V UART.

In order to translate the whole set of control lines of the UART you will need:

• 5 driver

• 3 receiver

NOTE:

The digital input lines working at 2.8V CMOS have an absolute maximum input voltage of 3.0V; therefore the level translator IC shall not be powered by the +3.8V supply of the module. Instead, it must be powered from a +2.7V / +2.9V (dedicated) power supply.

This is because in this way the level translator IC outputs on the module side (i.e. GE/GC 864 inputs) will work at +3.8V interface levels, damaging the module inputs.

NOTE:

In order to be able to do in circuit reprogramming of the GE/GC 864 firmware, the serial port on the Telit GE/GC 864 shall be available for translation into RS232 and either it's controlling device shall be placed into tristate, disconnected or as a gateway for the serial data when module reprogramming occurs. Only RXD, TXD, GND and the On/off module turn on pad are required to the reprogramming of the module, the other lines are unused. All applicator shall include in their design such a way of reprogramming the GE/GC 864.

Page 63

1vv0300915 Rev.2 – 2011-06-15

An example of level translation circuitry of this kind is:

The RS232 serial port lines are usually connected to a DB9 connector with the following layout:

9.4. 5V UART Level Translation

If the OEM application uses a microcontroller with a serial port (UART) that works at a voltage different from 2.8 – 3V,

then a circuitry has to be provided to adapt the different levels of the two set of signals. As for the RS232 translation there are a multitude of single chip translators. For example

Page 64

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

a possible translator circuit for a 5V TRANSMITTER/RECEIVER can be:

TIP:

Note that the TC7SZ07AE has open drain output; therefore the resistor R2 is mandatory.

NOTE:

The UART input line TXD (rx_uart) of the GE/GC864-QUAD V2 and GE864-GPS NOT internally pulled up with a resistor, so there

may be the need to place an external 47KΩ pull-up resistor, either the DTR (dtr_uart) and RTS (rts_uart) input lines are not pulled up internally, so an external pull-up resistor of

47KΩ may be required.

Care must be taken to avoid latch-up on the GE/GC864-QUAD V2 and GE864-GPS and the use of this output line to power electronic devices shall be avoided, especially for devices that generate spikes and noise such as switching level translators, micro controllers, failure in any of these condition can severely compromise the GE/GC864-QUAD V2 and GE864-GPS functionality.

NOTE:

In case of reprogramming of the module has to be considered the use of the RESET line to start correctly the activity.

The preferable configuration is having an external supply for the buffer level translator.

10. Audio Section Overview

The first Baseband chip was developed for the cellular phones, which needed two separated amplifiers both in RX and in TX section.

A couple of amplifiers had to be used with internal audio transducers while the other couple of amplifiers had to be used with external audio transducers.

To distinguish the schematic signals and the Software identifiers, two different definitions were introduced, with the following meaning:

• internal audio transducers  HS/MT (from HandSet or

MicroTelephone )

• external audio transducers  HF (from HandsFree )

Actually the acronyms have not the original importance. In other words this distinction is not necessary, being the

performances between the two blocks like the same. Only if the customer needs higher output power to drive the

speaker, he needs to adopt the Aduio2 Section ( HF ) . Otherwise the choice could be done in order to overcome the PCB design difficulties.

For these reasons we have not changed the HS and HF acronyms, keeping them in the Software and on the schematics.

The Base Band Chip of the GE864-QUAD V2 Telit Modules maintains the same architecture.

For more information and suggestions refer to Telit document:

• Audio settings application note , 80000NT10007a

10.1. Selection mode

Only one block can be active at a time, and the activation of the requested audio path is done via hardware, by AXE line, or via software ,by AT#CAP command .

Moreover the Sidetone functionality could be implemented by the amplifier fitted between the transmit path and the receive path, enabled at request in both modes.

1vv0300915 Rev.2 – 2011-06-15

10.2. Electrical Characteristics

TIP: Being the microphone circuitry the more noise sensitive,

its design and layout must be done with particular care. Both microphone paths are balanced and the OEM circuitry must be balanced designed to reduce the common mode noise typically generated on the ground plane. However the customer can use the unbalanced circuitry for its particular application.

10.2.1. Input Lines Characteristics

“MIC_MT” and “MIC_HF” differential microphone paths

Line Coupling AC* Line Type Balanced Differential input voltage ≤ 1,03Vpp @ Mic G=0dB Gain steps 7 Gain increment 6dB per step Coupling capacitor ≥ 100nF Differential input resistance 50KΩ Input capacitance ≤ 10pF

(*) WARNING : AC means that the signals from the microphone have to be connected to input lines of the module through capacitors which value has to be ≥ 100nF. Not respecting this constraint, the input stages will be damaged.

WARNING: when particular OEM application needs a Single Ended Input configuration, it is forbidden connecting the unused

input directly to Ground, but only through a 100nF capacitor. Don’t forget that the useful input signal will be halved in Single Ended Input configuration.

Page 69

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

10.2.2. Output Lines Characteristics

TIP:

We suggest driving the load differentially from both output drivers, thus the output swing will double and the need for the output coupling capacitor avoided. However if particular OEM application needs also a Single Ended circuitry can be implemented, but the output power will be reduced four times.

The OEM circuitry shall be designed to reduce the common mode noise typically generated on the ground plane and to get the maximum power output from the device (low resistance tracks).

WARNING:

The loads are directly connected to the amplifier outputs when in Differential configuration, through a capacitor when in

Single Ended configuration. Using a Single Ended configuration, the unused output line must be left open. Not

respecting this constraint, the output stage will be damaged.

TIP :

Remember that there are slightly different electrical performances between the two internal audio amplifiers:

• the “Ear_MT” lines can directly drive a 16Ω load at –

12dBFS (**) in Differential configuration

• the “Ear_HF” lines can directly drive a 4Ω load in

Differential configurations

• There is no difference if the amplifiers drive an external

amplifier

11. General Purpose I/O

The general-purpose I/O pads can be configured to act in three different ways:

• Input

• Output

• Alternate function (internally controlled)

Input pads can only be read and report the digital value (high or low) present on the pad at the read time; output pads can only be written or queried and set the value of the pad output; an alternate function pad is internally controlled by the GE/GC864-QUAD V2 and GE864-GPSfirmware and acts depending on the function implemented.

The following GPIO are available on the GE/GC864-QUAD V2 and GE864-GPS:

11.2. Using a GPIO Pad as INPUT

The GPIO pads, when used as inputs, can be connected to a digital output of another device and report its status, provided this device has interface levels compatible with the

2.8V CMOS levels of the GPIO. If the digital output of the device to be connected with the

GPIO input pad has interface levels different from the 2.8V CMOS, then it can be buffered with an open collector transistor with a 47K pull up to 2.8V, this pull up must be switched off when the module is in off condition.

11.3. Using a GPIO Pad as OUTPUT

The GPIO pads, when used as outputs, can drive 2.8V CMOS digital devices or compatible hardware. When set as outputs, the pads have a push-pull output and therefore the pull-up resistor may be omitted.

The illustration below shows the base circuit of a push-pull stage:

VDD

GPIO7

11.4. Using the RF Transmission Control GPIO4

The GPIO4 pin, when configured as RF Transmission Control Input, permits to disable the Transmitter when the GPIO is set to Low by the application.

In the design is necessary to add a resistor 47K pull up to

2.8V, this pull up must be switched off when the module is in off condition.

Page 74

GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide

1vv0300915 Rev.2 – 2011-06-15

11.5. Using the RFTXMON Output GPIO5

The GPIO5 pin, when configured as RFTXMON Output, is controlled by the GE/GC 864 QUAD V2 module and will rise when the transmitter is active and fall after the transmitter activity is completed.

There are 2 different modes for this function:

1) Active during all the calls: For example, if a call is started, the line will be HIGH during all the conversation and it will be again LOW after hanged up. The line rises up 300ms before first TX burst and will became again LOW from 500ms to 1s after last TX burst.

2) Active during all the TX activity: The GPIO is following the TX bursts

Please refer to the AT User interface manual for additional information on how to enable this function.

11.6. Using the Alarm Output GPIO6

The GPIO6 pad, when configured as Alarm Output, is controlled by the module and will rise when the alarm starts and fall after the issue of a dedicated AT command.

This output can be used to power up the module controlling micro controller or application at the alarm time, giving you the possibility to program a timely system wake-up to achieve some periodic actions and completely turn off either the application and the module during sleep periods, dramatically

reducing the sleep consumption to few µA. In battery-powered devices this feature will greatly improve

the autonomy of the device.

NOTE:

During RESET the line is set to HIGH logic level.

1vv0300915 Rev.2 – 2011-06-15

11.7. Using the Buzzer Output GPIO7

The GPIO7 pad, when configured as Buzzer Output, is controlled by the GE/GC 864 QUAD V2 module and will drive with appropriate square waves a Buzzer driver. This permits to your application to easily implement Buzzer feature with ringing tones or melody played at the call incoming, tone playing on SMS incoming or simply playing a tone or melody when needed by your application.

A sample interface scheme is included below to give you an idea of how to interface a Buzzer to the GPIO7:

NOTE:

To correctly drive a buzzer a driver must be provided, its characteristics depend on the Buzzer and for them refer to your buzzer vendor.

12. GPS Features (only GE864-GPS)

12.1. GPS Control

The GPS part of GE864-GPS can be driven by the GSM engine or by an external host. The circuital connections of the two configurations are showed in the subparagraphs below.

12.1.1. GSM Controlled Mode

The GPS part can be controlled by GSM part through specific AT commands (refer to AT$GPSAT on AT Commands Reference Guide, 80000ST10025a). The required electrical connections are showed in the figure below.

12.1.2. External Host Controlled Mode

Alternatively to the previous configuration, the GPS part can be controlled by an external Host so the GSM and GPS may be managed separately. In this case the Host must have at least two serial ports and two GPIO available for the control of GPS (see the figure below).

DAC_OUT AO Digital/Analog converter output

Function

The GE/GC864-QUAD V2 AND GE864-GPSmodules provide one Digital to Analog Converter.

The on board DAC is a 10-bit converter, able to generate an analogue value based a specific input in the range from 0 up to 1023. However, an external low-pass filter is necessary.

Voltage range

0 2,6 Volt (filtered) Range 0 1023 Steps

The precision is 10 bits, so if we consider that the maximum voltage is 2V, the integrated voltage could be calculated with the following formula:

Integrated output voltage = 2 * value / 1023

DAC_OUT line must be integrated (for example with a low band pass filter) in order to obtain an analog voltage.

Page 82

13.1.2. Enabling DAC

The AT command below is available to use the DAC function:

AT#DAC[=<enable>[,<value>]] <value> – scale factor of the integrated output voltage (0–

1023, with 10 bit precision), and it must be present if <enable>=1.
