To turn on the GE864-QUAD Automotive V2 the pad ON* must be tied low for at least 1

seconds and then released.

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

least 3 seconds.

The maximum current that can be drained from the ON* pad is 0,1 mA.

A simple circuit to do it is:

NOTE:

NOTE: NOTE:

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 GE864-QUAD Automotive V2 power

regulator and improper power on/off of the module. The line ON* must be connected

only in open collector configuration.

NOTE:

NOTE:NOTE:

NOTE:

In this document all the lines that are inverted, hence have active low signals are

labeled with a name that ends with a "*" .

TIP:

TIP:TIP:

TIP:

To check if the device has powered on, the hardware line PWRMON should be

monitored. After 00ms the line raised up the device could be considered powered on.

NOTE:

NOTE:NOTE:

NOTE:

It is recommended to avoid having any HIGH logic level signal applied to the digital pins

of the GE864-QUAD Automotive V2when the module is powered off.

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

• via AT command (see GE864-QUAD / PY Software User Guide)

• 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 GE864-QUAD / PY 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.

5.2.1. Hardware Unconditional Restart

WARNING:

WARNING:WARNING:

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 GE864-QUAD / PY, the pad RESET# must be tied low for at least

200 milliseconds and then released.

The maximum current that can be drained from the ON# pad is 0.15 mA.

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:

TIP: TIP:

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.

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

• The desired output for the power supply is 3.8V, hence there's not a big

difference between the input source and the desired output and a linear

regulator can be used. A switching power supply will not be suited because of

the low drop out requirements.

• 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 GE864-QUAD Automotive V2, 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 should be inserted close to the power input, in order to save

the GE864-QUAD Automotive V2 from power polarity inversion.

• 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 efficiency especially with the 2A peak current load represented by the

GE864-QUAD Automotive V2.

• 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 the switching frequency could also

generate EMC interferences.

• For car PB battery the input voltage can rise up to 15,8V and this should 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 usually suited.

• Make sure the low ESR capacitor on the power supply output (usually a tantalum

one) is rated at least 10V.

• For Car applications a spike protection diode should be inserted close to the

power input, in order to clean the supply from spikes.

• A protection diode should be inserted close to the power input, in order to save

the GE864-QUAD Automotive V2 from power polarity inversion. This can be the

same diode as for spike protection.

6.3.2.6.3.2.

6.3.2. Thermal Design Guidelines

Thermal Design GuidelinesThermal Design Guidelines

Thermal Design Guidelines

The thermal design for the power supply heat sink should 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):

4mA

•

Average current during idle (Power Saving disabled)

24mA

NOTE:

NOTE: NOTE:

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.

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's say

few minutes) and then remains for a quite long time in idle (let's 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 and hence the current consumption will be less

than the 500mA, being 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 can be enough to ensure a good thermal

condition and avoid overheating.

For the heat generated by the GE864-QUAD Automotive V2, you can consider it to be

during transmission 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 the GE864-

QUAD Automotive V2; you must ensure that your application can dissipate it.

6.3.3. Power Supply PCB layout Guidelines

Power Supply PCB layout GuidelinesPower Supply PCB layout Guidelines

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 GE864-QUAD

Automotive V2 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 GE864-QUAD Automotive V2 is 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 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 doesn't have audio interface but only uses the data feature of

the Telit GE864-QUAD Automotive V2, then this noise is not so disturbing and

power supply layout design can be more forgiving.

• The PCB traces to the GE864-QUAD Automotive V2 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 should 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 should be kept separate from noise sensitive

lines such as microphone/earphone cables.

When using the Telit GE864-QUAD Automotive V2, since there's no antenna connector

on the module, the antenna must be connected to the GE864-QUAD Automotive V2

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 Automotive V2, then a PCB line is

needed in order to connect with it or with its connector.

MODEM SERIAL PORTMODEM SERIAL PORT

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 doesn't need a

level translation is the 2.8V UART.

The serial port on the GE864-QUAD Automotive V2 is a +2.8V UART with all the 7 RS232

signals. It differs from the PC-RS232 in the signal polarity (RS232 is reversed) and

levels. The levels for the GE864-QUAD Automotive V2 UART are the CMOS levels:

9.2. RS232 level translation

RS232 level translationRS232 level translation

RS232 level translation

In order to interface the Telit GE864-QUAD Automotive V2 with 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).

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

NOTENOTE

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.

GE865 inputs) will work at +3.8V interface levels, damaging the module inputs.

NOTE:

NOTE: NOTE:

NOTE:

In order to be able to do in circuit reprogramming of the GE864 firmware, the serial

port on the Telit GE864 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 GE864.

An example of level translation circuitry of this kind is:

The example is done with a SIPEX SP3282EB RS232 Transceiver that could accept

supply voltages lower than 3V DC.

NOTE:

NOTE:NOTE:

NOTE:

In this case Vin has to be set with a value compatible with the logic levels of the module.

(Max 2.9V DC). In this configuration the SP3282EB will adhere to EIA/TIA-562 voltage

levels instead of RS232 (-5 ~ +5V)

Second solution could be done using a MAXIM transceiver (MAX218) In this case the

compliance with RS232 (+-5V) is possible.

Another level adapting method could be done using a standard RS232 Transceiver

(MAX3237EAI) adding some resistors to adapt the levels on the GE865 Input lines.

NOTE: In this case has to be taken in account the length of the lines on the application

to avoid problems in case of High-speed rates on RS232.

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

layout:

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 a possible translator circuit for a 5V

TRANSMITTER/RECEIVER can be:

TIP:

TIP: TIP:

TIP:

The logic IC TC7SZ07AE may be used as level translator. Note that the TC7SZ07AE has

open drain output, therefore the resistor R2 is mandatory.

NOTE:

NOTE: NOTE:

NOTE:

The UART input line TXD (rx_uart) of the GE864-QUAD Automotive V2 is 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.

A power source of the internal interface voltage corresponding to the 2.8VCMOS high

level is available at the PWRMON pin on the connector, whose absolute maximum

output current is 1mA.

A maximum of 9 resistors of 47 KΩ pull-up can be connected to the PWRMON pin,

provided no other devices are connected to it and the pulled-up lines are GE864-QUAD

Automotive V2 input lines connected to open collector outputs in order to avoid latch-up

problems on the GE864-QUAD Automotive V2.

Care must be taken to avoid latch-up on the GE864-QUAD Automotive V2 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 GE864-QUAD Automotive

V2 functionality.

NOTE:

NOTE: NOTE:

NOTE:

The input lines working at 2.8VCMOS can be pulled-up with 47KΩ resistors that can be

connected directly to the PWRMON line provided they are connected as in this example.

NO OTHER devices than those suggested should be powered with the PWRMON line;

otherwise the module functionality may be compromised.

It is important to consider that the added circuit must have consumption lower than

1mA.

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.

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

HSHS

HS/MT

(from

H

HH

HandS

SS

Set

or

M

MM

MicroT

TT

Telephone

)

• external audio transducers 

HF

HFHF

HF

(from H

HH

HandsF

FF

Free )

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 / GE864-DUAL V2 Telit Modules maintains the same

architecture.

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 GE864-QUAD

Automotive V2 firmware and acts depending on the function implemented. For Logic

levels please refer to chapter 8.

Description

The GE864-QUAD Automotive V2 module provides a Digital to Analog Converter. The

signal (named DAC_OUT) is available on BGA Ball C7 of the GE864-QUAD Automotive V2

module and on pin 17 of PL102 on EVK2 Board (CS1302).

The on board DAC is a 10-bit converter, able to generate a analogue value based a

specific input in the range from 0 up to 1023. However, an external low-pass filter is

necessary

Voltage range (filtered) 0 2,6 Volt

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

Integrated output voltage = 2 * value / 1023Integrated output voltage = 2 * value / 1023

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.
