ISSUE#0, - 21/02/06 2 Hardware Commands 2.1 Turning ON the GE863-GPS To turn on the GE863-GPS the pad ON# must be tied low for at least 1 second and then released. The maximum current that can be drained from the ON# pad is 0,1 mA. A simple circuit to do it is: ON# R1 Q1 Power ON impulse R2 GND NOTE: don't use any pull up resistor on the ON# line, it is internally pulled up.

Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 2.2 Turning OFF the GE863-GPS The turning off of the device can be done in two ways: • by software command (see GE863-GPS Software User Guide) • by hardware shutdown When the device is shut down by software command or by hardware shutdown, it issues to the network a detach request that informs the network that the device will not be reachable any more. 2.2.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 NOTE: don't use any pull up resistor on the RESET# line nor any totem pole digital output. Using pull up resistor may bring to latch up problems on the GE863-GPS power regulator and improper functioning of the module. The line RESET# must be connected only in open collector configuration. TIP: The unconditional hardware reboot should be always implemented on the boards and software should use it as an emergency exit procedure.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 3 Power Supply The power supply circuitry and board layout are a very important part in the full product design and they strongly reflect on the product overall performances, hence read carefully the requirements and the guidelines that will follow for a proper design. 3.1 Power Supply Requirements The GE863-GPS power requirements are: • Nominal Supply Voltage: 3.8 V • Max Supply Voltage: 4.2 V • Supply voltage range: 3.

ISSUE#0, - 21/02/06 - the electrical design - the thermal design. - the PCB layout. 3.2.1 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 3.2.1.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 3.2.1.2 + 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 efficiency especially with the 2A peak current load represented by the GE863-GPS.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 3.2.1.3 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 GE863-GPS module. The three cells Ni/Cd or Ni/MH 3,6 V Nom.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 battery may be damaged and even explode. Moreover for the constant voltage final chargers, the constant voltage phase (final charge) must not start before the battery voltage has reached its maximum value, otherwise the battery capacity will be highly reduced. The final charge can be of two different types: constant voltage or pulsed. GE863-GPS uses constant voltage.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 NOTE: For all the threshold voltages, inside the GE863-GPS all threshold are fixed in order to maximize Li-Ion battery performances and do not need to be changed. NOTE: In this application the battery charger input current must be limited to less than 400mA. This can be done by using a current limited wall adapter as the power source. 3.2.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 For the heat generated by the GE863-GPS, 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 GE863-GPS, you must ensure that your application can dissipate it. 3.2.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 4 Antenna The antenna connection and board layout design are the most important part in the full product design and they strongly reflect on the product overall performances, hence read carefully and follow the requirements and the guidelines for a proper design. 4.

Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 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. The signals in the UART connector on the EVK are: DCD RXD TXD DTR GND DSR RTS CTS RI GND 5.2 MODEM SERIAL PORT 2 (GPS CONTROL) This port is used to control the GPS part by the GSM part.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 5.4 GPS SERIAL PORT B (NMEA) This port is carrying out the GPS navigation data in NMEA 0183 format. The default configuration is 4800 bps, 8, n, 1 It is available on the following pins: PIN # 68 73 NAME TX_GPS RX_GPS DESCRIPTION GPS TX Data (NMEA) GPS RX Data (NMEA) TYPE CMOS 2.8V CMOS 2.8V 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. 5.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 This is because in this way the level translator IC outputs on the module side (i.e. GE863-GPS inputs) will work at +3.8V interface levels, stressing the module inputs at its maximum input voltage. This can be acceptable for evaluation purposes, but not on production devices.

Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 5.6 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, but since the translation requires very few components, then also a discrete design can be suited.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 NOTE: The UART input line TXD (rx_uart) of the GE863-GPS 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.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 6 Microphone The microphone circuitry is the more noise sensitive and its design and layout must be done with particular care. 6.1 Microphone line Characteristic and requirements The Telit GE863-GPS provides two audio paths for the microphone and the earpiece: the internal and the external audio paths. Only one of the two paths can be active at a time and it is selectable by hardware line AXE or by AT command.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 TIP: Due to the difference in the echo canceller type, the internal audio path is suited for handset applications while the external audio path is suited for car kit hands free. The headset applications should be made by using the external audio path but DISABLING the echo canceller by software AT command. If the echo canceller is left active with the headset, then some echo might be introduced by the echo cancel algorithm.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 10dB lower with respect to the calculated value for a nominal sensitivity. The corresponding reduction in signal level will be compensated by an increased voice volume of the talker which will speak louder because of the ambient noise. For the headset we shall distinguish two different types: the headsets having the microphone sustained close to the mouth and the headsets having the microphone on the earpiece cable.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 6.2 General Design Rules There are several configurations for the audio path, but the most effective difference is between balanced and unbalanced microphone. It is highly recommended to keep the whole microphone path balanced even if this means having 2 wires connecting the microphone instead of one needed (plus ground) in the unbalanced case.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 6.3.1 Balanced Microphone biasing The balanced microphone bias voltage should be obtained from a dedicated voltage regulator, in order to eliminate the noise present on the power lines. This regulator can be the same for all the audio paths. The microphone should be supplied from a capacitor multiply circuit.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 NOTE: The microphone sensitivity changes with the value of R2 and R3. Usually the microphones are characterized with 2kΩ biasing resistance, so try to keep the sum of R2 and R3 around 2kΩ. Refer to your microphone manufacturer for the mic. characteristics.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 6.3.2 Unbalanced Microphone biasing The unbalanced microphone biasing voltage should be obtained from a dedicated voltage regulator, in order to eliminate the noise present on the power lines. This regulator can be the same for all the audio paths. The microphone should be supplied from a capacitor multiply circuit.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 6.4 Microphone buffering As seen previously, a microphone shall be connected to the input pads of the GE863-GPS through a buffer amplifier that boosts the signal level to the required value. Again the buffered microphone circuitry can be balanced or unbalanced. Where possible it is always preferable a balanced mic. solution. The buffering circuit shall be placed close to the microphone or close to the microphone wire connector. 6.4.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 Gain = R604 R606 = R605 R607 The C636 and C637 capacitors are placed in order to cut off the gain at higher frequencies than the transmitted GSM band, the cutoff frequency (-3dB) should be 8 kHz in order to have -1dB at 4kHz. The cutoff frequency is given by the formula: freq.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 As a consequence the values of the capacitors C636 and C637 shall be: C636=C637= 1/ (2π*8000*R606)= 132 *10 -12 F A commercial value of 100pF is then chosen.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 6.4.2 Buffered Unbalanced (Single Ended) Mic. A sample schematic for a buffered unbalanced (single ended) microphone can be: The schematic does not include the required mic. biasing circuitry. For the biasing the same circuit as seen before can be used; to be noticed that the capacitor C3 on the unbalanced biasing circuit is not anymore needed if this Buffered design is used.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 As shown in the balanced buffered mic. the gain adjustments can be done by changing R719 R720 and R708 - R711 and as a consequence the capacitors C726 and C727. The bandwidth (-3dB) is given by the approximated formula (considering C725 >> C726) : 1 1 = [Hz] 2π * R719 * C 726 2π * R711* C 727 The buffer bandwidth at -3dB shall be 8kHz.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 R719 = (gain -1) * R720 = (1.5 -1) * 10 = 5 kΩ The commercial values of 15kΩ & 5.6kΩ are then chosen. As a consequence the values of the capacitors C726 and C727 shall be: C726= 1/ (2π*8000*R719)= 3.5 *10 -9 F C727= 1/ (2π*8000*R711)= 1,2 *10 -9 F The commercial values of 3.3nF and 1nF are then chosen.

Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 The resulting gain and high pass cut can be obtained with the formula: Gain = R3 R2 1 [Hz] 2π * R3 * C 4 And an example of internal Ear amplifier is: freq.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 Some amplifier require a low impedance load at high frequency in order to avoid auto oscillation, this can be made with a capacitor (100nF) in series with a resistor (15Ω). When designing your application, remember to provide an adequate bypass capacitor to the amplifier and place it close to the power input pin of the IC, keeping the traces as short as possible. 7.
Telit GE863-GPS Hardware User guide 1vv0300714, Rev. ISSUE#0, - 21/02/06 NOTE: The GE863-GPS audio path connected to the car kit hands free amplifier MUST be the external one (EAR_HF), otherwise the echo cancellation will not be done due to the difference in the echo canceller characteristics of the GE863-GPS internal audio path from the external audio path.
